My cat is maybe around 8 years old. She is a calico and very distant. She only wants to be around you if she wants to. Well the problem. A long time ago I had taken her to the vets because her bottom lip was swollen. It was around Christmas and I had thought she had eaten some poinsetta. Then after that I had thought she was chewing on my artifical tree. Well he gave her some medicine and still not sure what it was or if it even worked. And after all that the tree and plant weren't the problem. The lip went down and no more problems. Then one day she had a swollen lip again. Well she runs around like a mad cat so I had thought she bumped her mouth on something. That went on for a while and I don't really think it was that, I do believe that has happened to her but not really the problem. This has been going on for a long time. Now today she has a swollen lip again. Does anyone know what this could be? Because of how long this has been going on I can't really say its a food allergy either. Her teeth look fine or I think the vet would of said something to me. Any help would be appreciated.
