My 6 month old kitten needs help; raised third eyelids, vomiting, and respiratory sounds bad?

Her first symptoms were dilated pupils and raised 3rd eyelid, they have been that way for going on 3 weeks. Next symptom sneezing and vomiting. We took her to the emergency vet she stayed overnight, got x-rays (which showed nothing in her stomach, but showed feces in her colin). So they gave her anemia's to clean her out in case of blockage, IV for 24 hours, and a second round of x-rays (showing that they got everything but I tiny bit still in her colin).

Once home she is constantly going back and forth to her litter box and is urinating, throughout this she is still sneezing and her respiratory has gotten much worse (almost like a lot of snot moving around in her nose). We took her to our usual vet and over the past week and a half we have given her IV fluids under the skin and antibiotics. About a week ago she started puking up bug parts and stomach fluid (we thought there was nothing in her system).

Well now she is no longer vomiting bug parts and gets really really excited to eat and will, but promptly vomits it all back up. About 5 days ago she pooped a little bit over the course of 2 days about 3 marble size feces (maybe that little bit in her colin they were talking about). She has had her kidneys and liver tested and all came back normal. So as of right now her respiratory still sounds bad, and she eats but vomits it all back up, haven't seen her drink on her own, and her third eye lids are still up. She still walks around and responds to you, but is now getting very skinny and weak. We are now at a loss of what to do and have about exhausted most of our funds.. Please help with any suggestions

I started to say she could have a blockage, but based on her third eyelid still being up and still symptoms of URI and her continuing to vomit, it sounds to me as if she is still in the throes of an extremely virulent strain of upper respiratory virus, either herpes virus or calici virus. I had a cat like this, here she is on you tube 
She got better but I had to continue giving her fluids throughout. Plus I got a/d cat food from the vet and a bunch of syringes to force feed her the food. They told me I had to get at least one can of a/d in her each day. You can use the syringe to get the a/d food in there and swirl it around like a slushy to make sure it all gets into the syringe.

They also gave me antibiotics which I used and then squirted water in her mouth with the syringe to help get her to swallow the pills. She was very weak so I was able to wrap a towel around her and sort of lean on her in order to help do these things. I think my kitty was vomiting too because at one point they gave me sensitive stomach crunchies along with metronidazole. Also my kitty's third eye was up. She was so sick at one point she was walking to her litter box and she started to stagger, she could hardly make it and just stopped on the way and huddled up. I was petrified. 

You can tell if your kitten is seriously dehydrated by pinching the fur on the back of her neck. If it kind of stays rigid, she really badly needs liquids. And the a/d wet food is full of important nutrients.

Anyhow, I don't think she has a blockage based on what you describe. I think she is vomiting because she is really sick. The vomiting is the one thing that is disturbing. I hope they have tested her for FeLV, panleukopenia, and have looked at her to see if she has any symptoms that align with FIP.  But it could also be just a really super bad herpes or calici virus, these are the two most common strains of virus in cats and some of these 2 strains are way worse than others. 

You said she is eating but the question is how much and what is she eating? A lot of sick cats will eat a very small token amount and it is not enough. 

Sorry, some of these thoughts are disconnected but you get the picture. Find out from the doc how much food she should be ingesting daily and ask for a/d and how much per day. Have them sell it to you along with syringes and say you want to bring the kitty in when you pick up the food and can their vet tech please use the food you bought to show you how do do the syringe feeding to get enough wet food in her. Also have the vet tech show you how to get water in her too. 

You may already be doing this but if not, it is probably a good idea. If she is eating massive amounts of food and vomiting it, I would be asking the vet for verfication that the FeLV etc. are ruled out. The fact that her third eye is up and she seems to have massive upper respiratory to me, would mean that some independent blockage or tumor et al would be very rare. The only other thing would be if she ingested poison or if she were bitten by a spider, snake, whatever. I do not know enough about medicine to know if this would cause URI-like symptoms. Those two common viruses can cause these symptoms definitely. 

Really bad herpes or calicivirus can be really hard on cats. I was petrified that the kitty in that video above would die and I only posted it so people could see her and help me figure out what to do. She seemed to be better for a while and then relapsed. I can tell you cats always perk up after receiving fluids but then they go right back down again :-( so I wouldn't let the vet do that and send you on your way without more instructions and stuff like above.  

Here is my foster kitty, the sick one (Abby) several weeks later, healthy:   Happily my friend adopted her so I can look at her and know I did save a life. Good luck. and let us know more specifics about what, how much food etc. 

She may very well be constipated, which can cause an upset tummy which in turn would cause vomiting.  She could also not be able to tolerate the medication the doctor gave her.  Are you giving her an antibiotic daily or twice daily or what?  If it's clavamox, that's notorious for causing upset tummies in kitties. 

Call the vet first thing in the morning and ask for something to settle her tummy, or ask if you can give her Pepcid and how much, when (usually about 15 mins before feeding) and how often.  Also find out what kind of meds she's had.

Get some plain meat baby food from the store (no garlic, no onions, no ham) and some plain (clear) baby Pedialyte (full of enzymes) and found in the baby section.  Try feeding her some baby food and see if she'll keep that down.  Add a touch of the Pedialyte and mix with the baby food.  You can also try plain shredded chicken.  Just put a chicken breast in water with no seasonings and boil till done.  Shred and add in some of the broth until it's about the consistency of oatmeal.  Feed her some of that (maybe mix in some of the baby food & Pedialyte) and see if that will stay down.

To help with her congestion, you can steam her in the bathroom.  Just get the bathroom nice and steamy, turn off the water and then sit in the bathroom with her until the steam dissipates.  You can also try "Little Noses" (baby saline drops) in her nose to help get that stuff cleared out.  If you can confine her in one room, you could run a vaporizer 24/7 for her to help raise the humidity and ease breathing.

I really think you need to at least call the vet and talk with them about what's going on and how she's going downhill.  She really needs to be on some kind of antibiotic if she's not received any.  I would encourage you to NOT allow the vet to give her the Convenia shot, though.  Too many risks for her since she's already not feeling well. 
 

Agree with BarbB that it's time for you to take over feeding and hydrating your cat to get her through this acute phase of her illness. Intensive nursing can help her as much as veterinary care can now that you have gone through that route. Can you give her frequent very small meals, or are  you away from home most of the day? Syringe feed her only about 15cc of ad mixed with enough water to make it look like thick oatmeal (loose enough to through the syringe but not drippy) giving her a few cc's at a time then sitting with her and stroking her, talking to her,waiting a minute, then another few cc's.  Yes, it's very labor intensive but it gets the cat's stomach used to food again and is slow and small enough to be less likely to cause vomiting.  If you see your cat licking her lips a lot while syringe feeding her, stop because that's a sign of nausea.  Let her rest for a while, then begin again.  You can buy a bag of fluids, line and needles from your vet (it's cheaper if you buy online, but takes time) and learn to give her subq fluids. Subq fluids not only help the cat in medical terms but also make them feel good.  As BarbB said, calicii and herpes are terrible viruses and cause all kinds of damage, and they take a long time to shake off - in fact, sometimes herpes stays in the body and causes chronic URI. You have done a great job of caring for your cat, and I can well imagine having been there many times myself how you feel seeing her get thinner and weaker. Time for you to battle for your cat's life at a grass roots level, with veterinary support.

Also, can you put metamucil in her food?  It should help with her constipation and hard stools.
