Somewhat sudden personality change in cat

Hello all,

My husband and I are quite concerned about one of our cats, Eddie.  He is an almost 7-year-old Russian Blue/Maine Coon mix (although his appearance could easily pass for full Russian Blue).  We've had him since he was about 8 weeks old and he's always been the sweetest cat and has always loved everybody, including our large dogs (two golden retrievers and a black Lab) and other cats.  Gradually, over the past couple of months or so, we've noticed significant changes in his personality that have been getting worse over the last few weeks.  He has become aggressive and intolerant towards our other cats.  Whenever one comes near him, he will growl and hiss at them and will sometimes even swat at them for absolutely no apparently reason.  Sometimes, one of the other cats will just be minding his own business and he will run up to them growling and will swat at hiss at him.  He has NEVER done this before ever.  He has always gotten along great with our other cats.  Lately, he is even hissing and growing at the dogs, who he used to always LOVE.  He would always sleep with them and would nuzzle up against them.  Now, he just hisses at them like he does the cats.  Other than all of this, Eddie is acting completely normally.  He is eating, drinking using the box, and looks perfectly healthy.  All of our cats are indoor only cats and never go outside.

I will admit, our lives have been a bit chaotic recently and we wonder if that could be contributing to his change in behavior.  Back in June, we lost our oldest cat, who was 12, to renal disease.  He passed away at home and it was very rough on us.  Eddie was fairly close with him.  They used to sleep together a lot and were frequently hanging out together.  In August, we ended up adopting two male kittens (we were only going to get one, but got talked into two).  This put us at 5 cats.  At first, Eddie seemed okay with the babies, but now he just growls and hisses at them.  Also, we temporarily have one of my husband's co-worker's cats, who is about 15 years old, while he is away on an extended business trip and he had no one else to watch him, so we agreed to let him stay with us until he returns.  Eddie doesn't like him either.  Another possible trigger is that for the past couple of months, we have been having our home remodeled, so we have had several contractors in and out of our house remodeling our kitchen and installing new flooring throughout the rest of the house.  This remodel was only supposed to take 2-3 weeks and instead ended up taking about 2 months due to several delays.  We were not happy at all, but it is now finally complete.  When the contractors were here, we had to keep the cats in one of our spare bedrooms so that they wouldn't be in the way and so they wouldn't accidentally get outside.  We're not sure if this could have something to do with Eddie's irritability as well.

The remodel has been complete for about 2-3 weeks now and our lives are basically back to normal finally, but Eddie is still very irritable and aggressive towards our other pets.  We thought he would settle back down now that everything has quieted down, but he hasn't.  We are extremely frustrated and don't know what to do.  This is not the Eddie we have known and loved for nearly 7 years.  We have no idea where these behavioral changes have come from.  This just isn't like him.  Like I said, he used to love EVERYONE, even the dogs.  My husband really thinks that it is because he misses our cat, Bailey, who passed away 5 months ago, but I just don't know.  I'm sure he misses him, but I don't know if that would cause his drastic change in behavior.  He is not aggressive towards us, but he doesn't come up to us for attention like he always used to and is basically isolating himself.

Does anyone have any advice or tips regarding this?  We just don't know what to do!

Stress could definitely be a cause. Some cats are very sensitive to change and if they can't take their upset out on the thing that's changing, they'll often try to take it out on other cats in the household. You could try a calming diffuser or spray. Something like Feliway.

On the other hand, sudden changes in temperament are often the sign of an underlying health problem.  He's certainly not old, but he's not a kitten either so it might not be a bad idea to take him to the vet for a check-up. Cats hide pain and discomfort really well and it could be that the only sign he's giving is his irritability.

I definitely agree that it's most likely stress from all of these changes we've had.  He was never like this prior to everything that we've had going on in the recent months, starting with his friend, Bailey, passing away at the end of June and then the arrival of the new kittens in August and then in September the arrival of the 15 y/o cat we are taking care of while his owner is away, plus the remodel on our house, which definitely stressed my husband and I out quite a bit, so I'm sure Eddie picked up on that, which probably stressed him out even more.  Physically, I think he's fine.  He hasn't lost any weight and is still eating and drinking completely normally and his nose is always cold and wet.  I just hoped that he would start to go back to his old self now that things have finally started to get back to normal around here.  We'll probably see how he is in a couple of weeks and if there is no change by then, we'll call our vet.

My cat, Olive, also has had a sudden personality change. She was injected with Convenia and DepoMedrol a month ago, and she nearly died. Long story short, I've pretty much nursed her back to health, and she was returning to her normal self, but a week ago, a vet tech was here just to meet her, and she really hasn't been the same since. I'm sure the poor thing is  reacting the smell of the vet office, which he brought into her safe home. (She usually is the welcome wagon to ANYONE who comes in, but with him, she ran under the bed.) (He came over as she needs a medicine for three weeks for a separate issue, and I was thinking of hiring someone to do it instead of doing it myself, as she's pretty new in my home.)

I'm heartbroken that my sweet Olive even seems to be afraid of me now, as she's not seeking the affection from me at all. I've only had her for five months (she's two and a half) and have been through the mill with her, emotionally and financially. (She was at the vet seven times, and I've spent at least $1200 on all this, probably more.)

The reason I'm responding to you isn't so much to tell you my story, but to give you an idea that I'm thinking of using myself, which is to give Olive the appetite stimulant she was on a few weeks ago. It's call Mirtazepine, and it's actually an old human antidepressant (Remeron). Not only does it spark cats' appetites, but it also makes them very affectionate, as it stirs up the serotonin in their brain.

If Olive's behavior continues, I think I might give it to her, just to reset the brain, so to speak. Obviously, I'm not sure it will work, but it definitely made her even more affectionate than she already was.

The normal dosage for cats is 1/4 of a 15 mg pill, but if you go this route, I would recommend 1/8 of a pill, which is the latest recommendation among vets. Olive initially got 1/4, but it made her a bit nuts in that she meowed a lot and was totally restless for hours. The 1/8 dosage was just fine.

Anyway, just putting it out there. If you find any solutions for your own cat, please let me know, as I'm in the same boat! I'm on the verge of talking to a cat behaviorist, but that would be another $250 or so. I'm really at my wit's end with all I've been through in the last month.

And I'm so sorry about your situation, too. I get it!

P.S. I've also pulled out my sprays that I bought from the Jackson Galaxy web site...Stress Stopper and Scaredy Cat. I'd purchased them last year for a foster cat I'd had here. I also have the Feliway thing plugged in, but that doesn't seem to be doing anything. I have the spray version, which I'll try on the couch, along with the sprays I just mentioned. I'll let you know if I have any luck!

I don't have a lot of advice either. It could definitely be stress related. Is it all cats or one particular that he has a problem with? It could just be that he's had an issue with one particular kitty.

The other thing to check is redirected aggression. My boy gets very angry just like this when other cats have been coming into our yard and takes it out on his sister and us sometimes.

I also tried feliway and it did help some and is definitely worth a try (although I'm another one who has had to resort to medication after battling for over a year with his anxiety and aggression, but it wasn't a step I took lightly and he's on a miniscule dose)

It's essentially all of the cats and even the dogs occasionally as well, who he has always loved.  It's not targeted at just one cat in particular.  It's not all the time that he does this, but a good portion of the time.  He definitely does it to the 2 new kittens, who we have now had since August, as well as the other cats.  I hear him growling and hissing intermittently throughout the day and night.  He basically has just turned into a jerk, almost like a bully to the other cats and he never used to be like this at all.  The other cats could be just minding their own business and not even looking at him and he will still growl/hiss at them as he walks by them.

I did pull out my Spirit Essences elixirs last night, and I have to say, she did calm down. I think they had an effect on me too. I also pulled out two Bach Flower essences that I had custom made for each of us when she first got sick.

These are the formulas made by Jackson Galaxy, the cat behaviorist who stars in the Animal Planet show "My Cat From Hell." If you search any of these products on Amazon, you'll see that the reviews are basically split between either five-star or one-star. There's very little in the middle, which means that they work brilliantly for some and not at all for others, which is true of any basic medication or treatment modality.

He has something called "Bully Remedy," which might be worth a shot. I personally have had success with the Bach Flower remedies for myself, and these Spirit Essences formulas had a wonderful effect on Olive last night. I'll keep using them for the next few weeks and see how she does. I even ordered "Safe Space" last night off his site, to add to the mix.

I tried copying the link to this page, but it's not allowing it for some reason, so just search it on the web. I would definitely order it directly from his site, as that's where all of the explanations are for each remedy. Might be worth a shot!

Having a really hard time typing on this board tonight. Will type a few words, then everything stops. Very strange.
