My 9-month-old cat has a swollen lip, diarrhea, and sneezes. Is it his new food?

Yes, suddenly changing food can cause diarrhea, and if the diarrhea caused a lot of irritation, it could cause redness or swelling. Keeping the area clean with a pet/baby wipe and returning Quinn back to his normal food is best. If the diarrhea continues for more than a few days, he seems in distress, the swelling is really bad or he can't go potty at all, vet care is best.

It is most likely that he has a viral form of cat flu, this is really common especially in cats who have been in shelters. There is no treatment for the virus as such, if he seems particularly unwell it may have become bacterial so a trip to the vet and sone antibiotics may be required. The diarrohea could be infection or just inflammation from stress/ intolerance etc. If it is intermittent I would try a gadtroitestinal food and you could give a pribiotic. If it becomes regular you should go to the vet.

I don't think the diarrhea has anything to do with the upper respiratory infection. I would recommend that you call the vet. They may want to test for intestinal parasites or may be concerned about a different bacteria or virus causing the diarrhea. I wouldn't change any food right now, since a sudden change may make the diarrhea worse. If he develops vomiting, decreased appetite, or lethargy, I would definitely have him checked out by the vet.

This may be the start of an upper respiratory disease. They usually do have a fever and swollen lymph nodes (possibly causing the face to swell) early in the infection, which will make them feel bad. They also tend to avoid eating and drinking early in the infection. It appears that both sides of Blue's face are swollen, but if it happens that only one side is swollen, then this can indicate a local infection/abscess. This can happen with bite wounds, other puncture wounds, or dental disease. I wouldn't be too concerned about this being an emergency, but it's best if you can get Blue to a vet within the next day or two. While these infections are often mild, they can become complicated, which will make things much worse. The vet would be able to narrow-down the cause of this and prescribe the necessary treatment to make him feel better and keep the infection from getting worse. I hope this helps and Blue feels better soon.

It could be potentially related to diet, but, considering the persistence of the signs,these episodes may be related to parasite infestation or a bacterial infection. I would suggest a check up at your local veterinarian, a fecal sample may be helpful for your vet. If already treated for worms, antibiotics may be needed.

Poor guy. I would first suspect that he may have either a bacterial infection or a parasite infection. Have his stool tested by your vet to determine which is present so that he can get the proper treatment. Poor guy. I hope Sammy feels better soon. In the meantime offer him tuna and white rice to help settle his stomach and plenty of water to help prevent him from getting dehydrated. Diluted Pedialyte (non-flavored) can also be given via syringe. Best wishes and take care.

Hi there. Millie looks like a very cute kitten. If her symptoms started immediately after the change in diet it is likely it is from the diet change. You can try going back to her previous diet, give it a few days, and see if her symptoms improve. If you go back to her previous diet and she stops eating, becomes lethargic and/or continues having vomiting and diarrhea I would recommend to have her examined by her veterinarian. Best of luck with Millie.
