Why is my cat's third eyelid swollen and neck lymph node enlarged?

Updated on September 23, 2025

Pet's info: Cat | Domestic Shorthair | Male | unneutered | 2 months and 26 days old | 3 lbs

My cat had a swollen inner eyelid in his right eye and a swollen lymph node in his left neck. Any idea what could be going on?

Cats will have raised third eyelids for any reason that makes them not feel well. Enlarged lymph nodes can be from allergic disease, infection or cancer. If these do no resolve in a couple of days or Jerry is showing any other signs of illness I would recomend a vet visit for Jerry to have an exam to see what is going on.
