Cat on antibiotics: red nose bump, breathing, diarrhea, not eating?

Poor Sneakers! If she is having persistent sneezing and nasal discharge even after treatment with antibiotics, and you are also seeing a bump of some kind inside her nostril, I would be concerned that she may have a nasal tumor or foreign body of some kind in her nose. If your veterinarian does not have any suggestions for further work-up at this point, I would recommend asking for referral to a specialist for rhinoscopy (looking at the inside of the nasal cavity with a small camera), as well as other testing if needed such as a bacterial or fungal culture, biopsy of the lump, etc. to try and get a diagnosis.

I would recommend uploading a picture of Yui's nose for us to see. You can resubmit the question and upload up to 3 pictures. If it is not resolving then the next step would be a biopsy of the lesion. That would give us a definitive answer as to what is going on.

Hi. Yes, this could be an access. I can't say that for sure, but if the bacteria are resistant to the medications prescribed, an abscess can still form. I recommend getting her rechecked so you can find out what that lump is.

I would be surprised if your sister’s illness spread to your cats as I can’t think of any human virus that would cause diarrhea or upper respiratory signs that could be spread to cats. It’s possible that the cats have something contagious however. The diarrhea could be viral or due to parasites. The eye and nose discharge sounds like symptoms of a viral upper respiratory infection. If the discharge is clear antibiotics might not be necessary. I would recommend having a vet examine your cat - they can prescribe appropriate medication.

I think this looks like a scrape or potentially the beginning of a skin infection. I can't think of a link between diarrhea and a skin lesion like this. If this spot gets larger or you notice more skin lesions I'd recommend rechecking with your vet. If it is a scratch it should resolve without treatment in a week or two.

I would recommend seeing the vet. At this point even if the diarrhea was initially related to the antibiotics Jasper may now have a disruption of his normal intestinal flora that requires additional treatment. It's also possible that the diarrhea is unrelated to the antibiotics and instead is due to intestinal parasites or a food sensitivity. If you wait until he stops eating or loses weight he may require more intensive treatment so I'd recommend making an appointment to see your veterinarian this week.

Thanks for using Petco Pet Education Center, formerly Petcoach! Since you are in day 1 of the antibiotics I think it would be fair to give it a bit more time to see if Musika gets better. You can try to entice his appetite with things like tuna, tuna water and chicken. If his appetite does not improve by tomorrow, let your veterinarian know as anorexia can be detrimental to a cat's health. Good luck and have a great day!
