My cat's nose is swollen, sneezing, and scratching. What should I do?

It does sound like your cat is experiencing an allergic reaction to the powder, and I would have him seen by a vet immediately. He needs veterinary treatment now, please take him into an ER vet or find a vet on call to see him now.

It is extremely concerning that Peanut has a swollen face and ragged breathing, and I would be very concerned she could be experiencing an allergic reaction. It could also be that Peanut was attacked by another cat if she's allowed outdoors, and that could be causing the swollen face, breathing difficulties, and vomiting. When a cat is having problems breathing, it is a medical emergency and she has to be seen by a vet now. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

Oh no, poor Ollie. The swollen face could be from an accident, getting into something toxic, a fight, or an allergic reaction. I cannot say what is causing his symptoms without seeing him in person, but I can say for sure he needs to see a vet now to diagnose what is causing it. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.

I would guess that Greggy has an upper respiratory infection. This can cause eye swelling and discharge from conjunctivitis along with sneezing and nasal discharge. A scratch on the eye might also be possible. If there are absolutely no vets around today (you might want to try travelling to see an emergency vet) then I'd recommend keeping Greggy comfortable until he can see a vet - he may need antibiotics and prescription eye ointment. You should make sure he's eating and drinking - you may want to try offering canned food if his appetite seems decreased.

I am sorry to hear about your kitten! I would recommend bringing her in for an exam at your vet. If the swelling is progressing tonight or she develops any difficulty breathing I would get her to the emergency vet. We could have swelling do to an allergic reaction from an insect bite or exposure to any other substance/plant (most of the time we don't see a mark/know the cause) but I would also want to check for things like an abscess or infected tooth causing swelling. It sounds like he may also have a mild upper respiratory infection (like us having a cold) that he has passed to the other cats.

Poor Leah. She could have a severe upper respiratory infection or could have something stuck in her nasal cavity causing the swelling and discharge. Without seeing her in person, I can't say for certain. When cats have issues with their nose like you are describing, they often stop eating because they can't smell their food. You want to avoid that happening, so I would take her into a vet this weekend to get this diagnosed and treated. Best of luck.

That sounds serious. I recommend to get Kitty into see the veterinarian today. Fungal infections and trauma are the main things that come to mind although a tumor or a significant reaction to a foreign object in the nose may look like this. She needs to be evaluated and start the process of figuring out whats causing all this. Unfortunately, there's really nothing you can do as the process is internal. I hope this points you in the right direction. Please feel free to post any additional questions.
