Hi everyone, 


I posted a question here about a suspected herniated disc in my 5 year old cat, Pumpkin, about three months ago.  After 10 months of seeing a wide variety of doctors and specialists, we finally have a diagnosis: our cat had a stroke last July.  I am writing this post in case it is helpful to someone else in a similar situation.  

Pumpkin was a stray at my daughter's high school and was about 9 months old and feral when we trapped her.  She has always been in good health once we got her weight up to normal and had her dewormed, vaccinated, etc.

On July 4, 2014, Pumpkin was in the back yard with me and was fine one minute and nearly comatose-acting the next minute.  She was sitting in a hunched forward position with her head low and her eyes squeezed shut.  She didn't even open her eyes when I talked to her.  I immediately took her to a large emergency/specialty clinic in our area.  The emergency vet did CBC/chemistry, FeLV/FIV test and x-rays.  All were normal.  However, while the vet and I were discussing Pumpkin, she had two small seizures.  The seizures looked like this:  her eyes were squeezed shut, she was sitting in the "loaf position" and she trembled significantly for about 20 seconds.  The veterinarian gave her subcutaneous fluids and said to watch for trouble urinating, difficulty breathing, or any unusual neurological activity.  None of those symptoms followed, but she has never been the same cat since that day.  She is a much more lethargic cat, completely lacking the high energy and mischievousness she once had.  She has also been far more irritable, both with us and with our other animals (4 other cats and a dog).  She seems very fearful of being touched by either us or the other animals.  She also no longer jumps to her favorite high spots that she used to love.  Her appetite is normal.

I won't bore you with all of the veterinary appointments we have had since that day.  I will tell you that, at one point, we had spent a total of $8000 and still did not have a diagnosis.  Over the 10 months, she has had a ton of blood work, ultrasounds and  x-rays.  She was tested for a wide variety of illnesses including toxoplasmosis, FIP titers, pancreatitis, various muscle diseases, and I can't remember what else.  At various times over the past 10 months, she has been on pain medications, anti-inflammatories and steroids.  The symptoms that have concerned me most have been the way her breathing looks labored whenever she sleeps and the permanent irritability.    Whenever she sleeps, she looks like she is in pain.  With each breath, she hunches up her shoulders and squeezes her eyes shut.  When I originally posted here in February, a surgeon had diagnosed her with a likely ruptured disc and wanted to do back surgery.  The surgeon had based the ruptured disc conclusion on Pumpkin's sensitivity when her back was palpated and her sluggish back left leg.  She thought these were the effect of a ruptured disc pressing on a nerve.

I am so grateful we pursued a second and third opinion.  I found that the two specialists we consulted were different that the other vets we had seen in that they visually observed Pumpkin far more extensively and asked many more questions than all the other vets had.  The two doctors from whom we sought second and third opinions did not know of each other's conclusions, yet they came to the exact same conclusion.  The second opinion was by a wonderful internist/oncologist named Dr. Cheryl Harris who, after watching Pumpkin walk and conducting several neurological tests with her reflex hammer, was sure that we were looking at a neurological problem.  (Dr. Harris diagnosed my dog's bladder cancer years ago after many trips to other vets who were not able to figure out what was going on.)  She noticed that Pumpkin was goose-stepping with her back left leg, lifting it higher than needed before placing it down with each step.  She explained that Pumpkin would be doing this because she had less sensitivity in that leg, making her less sure of where she was placing it.  She also looked at videos I had taken of Pumpkin's breathing when she slept and thought the jerkiness and eye squeezing indicated a neurological problem.  Both of these symptoms made her suspect that these were the residual effects of a stroke.

Today, I met with a renowned neurologist.  His brilliance is richly deserved.  He is a teacher at Ohio State University's Veterinary School, in addition to his neurology consulting work.  I had been given his name by 3 different veterinarians.  For anyone who might need it, his name is Dr. William Fenner.  He thoroughly examined Pumpkin and explained that he was quite positive she had suffered a stroke back in July.  Here are some of the activities he did that brought him to that conclusion:  He brought a hand from behind Pumpkin's head on her left side, and she barely noticed.  When he brought his hand from behind on her right side, she flinched dramatically.  When he touched the left side of her nose, she didn't react.  When he touched the right side of her nose, she jumped away.  When he had her jump up on a table, her left leg lagged behind her right.  As he watched the videos of her sleeping, he noticed her left eye squeezing shut more dramatically than her right eye as she breathed in that jerky manner. He asked many questions, such as whether her breathing jerkiness got worse when she was more tired/stressed (it increases dramatically on those occasions, especially after visits to vets).  I also mentioned that she only lays on her right side now, never on her left side.  

I'm sure I've forgotten some of our conversation, but he said we could have an MRI done, but he was 100% sure an MRI would show she had right frontal lobe damage.  The very likely explanation is that it was caused by a stroke.  The most typical residual effect of a frontal lobe stroke is a personality change, most often a dramatic increase in aggression.  Pumpkin's increased aggressiveness is much less than that of most cats who have suffered a stroke, most likely because she had such a sweet disposition before the stroke.  She never harmed anything.   She was the type to lay down to watch a moth or a butterfly with great interest, but she never approached or harmed anything.  The lack of reactivity on the left side of her face is caused by diminished vision and sensitivity due to the stroke in the right side of her brain.  A stroke on the right side of the brain causes damage on the left side of the body, and vice versa.  

The goose-stepping she does with her back left leg and the way the left leg lags when she jumps are both evidence of the right brain stroke.  The jerky breathing and eye squinting when she sleeps are actually seizures that are occurring when she sleeps.  That horrified me, but the neurologist doesn't think this is causing her pain, even though it is so disturbing to watch.  He asked me many questions and from my answers concluded that her condition is static, which means that she is basically stable.  He discussed treating the seizures with a twice a day pill, but thought having to administer the pill twice per day (Pumpkin is terribly hard to give pills to) would stress Pumpkin more than benefit her.  He suggested we enter a period of "watchful waiting."  Hopefully, she will remain as she is and not decline in any way.  Of course, if her seizure activity increases or other symptoms develop, we will have to re-evaluate what to do.  

After 10 months of worry, we are so grateful to have had the second and third opinions by brilliant specialists.  While we are very sad that Pumpkin suffered the stroke, we are thankful she survived it and still has some quality of life.  My main points in writing this were to explain what a stroke in a cat might look like in case you are seeing similar symptoms in your own cat and to encourage people to seek second opinions by highly-esteemed experts.  The very knowledgeable eye of an expert can often be more cost-effective than extremely expensive tests in the hands of a less seasoned professional.

Thank you for sharing.  This is so strange.  Almost like a human stroke.  I've heard of many cat strokes, and none of them were affected in this way. 

I know what you mean about trying to give her pills, we've got one who needs to be pilled too, and I swear she has the jaws of a pitbull
.  Luckily, I just found out that her meds can be compounded into an injectable, and since my hubby is a retired nurse, we're going to try that route.  If it doesn't work, nothing lost, since currently she isn't getting her meds anyway.  Have you tried wrapping her pills in pill pockets or just using anything soft like Whiska Lickins soft treats or even cream cheese?   That works with SOME cats.  Not ours, naturally, because she has a tendency to chew everything to death
  But it might work with Pumpkin.

Anyway, many vibes for your little one and hoping she "maintains".

Mrsgreenjeans,

Thank you so much for your kind note. Pumpkin's symptoms did not seem like those I read of other cats who had strokes. However, the neurologist explained that people often don't even realize their cats have had strokes. They will simply see a sudden change in the cat's level of aggression (sudden development of scratching and biting) and not realize that these behaviors developed as the result of a stroke. The neurologist said that many of these cats are euthanized after the behavior change.

In 9 out of 10 cases, the neurologist said that the cause of the stroke is never discovered. Since Pumpkin seems reasonably content for the time being, we will leave things as they are. I would have been willing to try to put the pills in cream cheese or another treat, but Pumpkin is very picky and will only eat dry food.If I see any increase at all in her seizure symptoms as she sleeps, I will absolutely attempt the seizure medications. It isn't too hard to give her liquid medications, but pills are almost impossible to administer. Unfortunately, since we trapped her as a feral, she has never been that trusting of humans. After all the trips we have taken to the vet, she trusts me less now than ever. She usually hides in a dark corner of the basement after every vet trip, and runs when she hears my voice for a couple days after each vet trip. It breaks my heart since, of course, I want nothing but to make her well and happy.

Thank you so much for your kind thoughts.

All my best to you and your pets,
Julie

I am sorry to read of Pumpkin's misfortune, but I was very interested in your detailed description of her symptoms, etc., because of my own cat, Shadow's problem:

http://www.thecatsite.com/t/297386/vestibular-disorders-in-cats

I was curious to see if my cat had any of your cat's symptoms, but he doesn't.  The thought of stroke had also occurred to my husband and I. but our vet has mostly ruled that out.

I do hope and pray that your baby will improve.

AngelinaCat,

Thank you for your sweet note.  I read your post about Shadow and to me, it sounds more likely that he had a head injury as a result of that jump.  Obviously, I am not a vet, but like you, I have spent a great deal of time researching cat illnesses/conditions, as well as taking cats to a wide variety of veterinary specialists.

Could Shadow have hit his head on the headboard?  Maybe he simply landed in such a way that he hurt his head.  You've probably already found information on anisocoria, the condition where one of a cat's pupils is larger than the other.  Your vet saw that in Shadow, but the question is, why is one of his pupils larger than the other?  In this link that talks about anisocoria (http://pets.thenest.com/feline-cat-behavior-changes-uneven-pupils-10582.html), there is the following information:

When your kitty has two differently sized pupils, this is called anisocoria. Even if she’s not showing any other symptoms, it’s important to get her seen by your vet as soon as possible. Your feline gal might have a head injury that’s causing one pupil to expand or shrink abnormally. This condition can cause some noticeable behavioral changes in your kitty as she tries to adjust to changes in vision or head and eye pain.

The other thing that makes me wonder about a head injury is Shadow's walking difficulties, his staggering, drunken sailor walk when you brought him home after the vet's observation.  You also said he seems unsure of his hind legs placement.  That sounds like some kind of disconnect between the messages his brain is sending and his back leg movements.  That could be caused by brain trauma if he hit his head during that jump.

The reason I'm leaning toward some kind of head trauma as being the reason for the different sized pupils and the unsure back leg placement is that they followed immediately after the jump.  Shadow was completely normal before that jump.  

Is Shadow still improving today?  I know your post said that you were taking him back to the vet tomorrow (Friday).  Hopefully, Shadow is improving daily.  If symptoms remain, I would get an appointment with the best neurologist you can find.  I wish you lived near us in Ohio.  We were blown away by Dr. Fenner's observation and analysis of Pumpkin.  

I will say prayers for Shadow and send positive energy your way.  I hope he continues to improve rapidly until he is completely himself again.   
 


All my best,

Julie

AngelinaCat,

I just wrote a long reply to your post, but when I submitted it, I received a message that it was sent for moderation because I had included a link in my post.  I will try to briefly paraphrase what I said in case the post does not get approved and posted.

It sounds to me like Shadow suffered a head injury in that jump.  Of course I am not a vet, but I have spent a lot of time researching cat illnesses/conditions and taking our cats to a wide variety of specialists.  Your vet diagnosed Shadow as having a vestibular disorder based on his different sized pupils.  I'm sure you have already seen that the condition of different sized pupils is called anisocoria.  But as you said, what caused the pupils to be different sized?  I won't link to the article so this post doesn't get booted again, but this was written in the article:

When your kitty has two differently sized pupils, this is called anisocoria. Even if she’s not showing any other symptoms, it’s important to get her seen by your vet as soon as possible. Your feline gal might have a head injury that’s causing one pupil to expand or shrink abnormally. This condition can cause some noticeable behavioral changes in your kitty as she tries to adjust to changes in vision or head and eye pain.

The other thing that makes me wonder about a head injury is Shadow's initial drunken, staggering gait and his continued unsure placement of his hind legs.  That makes me suspect a disconnect between the messages his brain is sending and the movement of his legs.  

I know your post said you are going back to the vet tomorrow, Friday.  I hope that Shadow's condition has continued to improve.  If it does not completely resolve, I would get an appointment for him with the best neurologist you can find.  I wish you lived in our area because we were blown away by Dr. Fenner's examination and analysis of Pumpkin and would recommend him unconditionally.

I hope that Shadow continues to rapidly improve until he is completely well again.  In the meantime, you and Shadow are in my prayers.  I'm sending you positive energy and warmest regards,

Julie

Hi Julie:

Thank you for your response and the information.  I am definitely watching Shadow.  He is continuing to improve to the point that he trotted almost normally across the floor last night.

With that said, I took him to the vet this morning, and he was impressed with Shadow's progress.  We both are currently thinking that Shadow had a low-grade inner ear infection that finally manifested itself the way it did on Monday.  The vet administered a two week long antibiotic Monday and it is still working.  The vet had observed redness inside one of his ears, and then today observed a couple of swollen lymph nodes.

Shadow's appetite has improved greatly.  Where I used to put out a teaspoon of Fancy Feast or something like that and he would pick at it, now he is gobbling it down.  Now, to be fair, we have two totally outside cats, and Shadow and his brother can come and go, so I really  don't know how much they have eaten of the outside food.

But he seems to be on the mend, and I have let him outside to be with his brother.

Thank you for your prayers and concern, and I am sending prayers and positive vibes in your Pumpkin's direction!

AngelinaCat,

Just in case you didn't see my post in your thread about Shadow, I am soooo thrilled to read about his progress.  A middle ear infection makes so much sense and antibiotics will completely eradicate it. Good exam on your vet's part (catching the red ear and swollen lymph nodes).  Your post made my week!  Continued prayers and good karma coming your way for a full recovery.

Julie
