Poor Little Bit! If it's his lymph nodes that are swollen, he could have an infection in that area causing the swelling. It could also be a virus, immune mediated disease, allergies, and even cancer though that would be rare in a cat his age. This is something that needs to be checked out by the vet, so give his vet a call now to make him an appointment. Best of luck, I hope this helps!

    Thanks for using Petco Pet Education Center, formerly Petcoach! You could be referring to an enlarged lymph node, a mass or even an abscess. I recommend that you have Buddy evaluated by your veterinarian for further assessment and treatment. How this is approached, will depend heavily on the diagnosis. Good luck and have a great day!

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Smokey! If he goes outside it could be an abscess from being bitten by another cat during a fight. You didn’t indicate his age but a tooth root abscess or a tumor is also possible. I would have Smokey seen by your Vet so they can evaluate the swelling. Abscesses are treated by lancing and flushing the wound and prescribing antibiotics. If they suspect an infected tooth he will need a dental and the tooth extracted. I hope this helps and I wish Smokey the best!

    Hi. This sounds like it may be an abscess, or even an inflamed lymph node from an infection. These don't always cause pain or irritation. Pets though are good at not showing pain. So even though we think they aren't painful, they could be. So, I would get little Sage checked out to be sure all is ok and get treatment if it is an abscess.
