This morning my cat was limping and crying in pain, so i took him to the vet. I found out that he actually has a type of infection in his knee. He has no wounds on his knee and it was all very sudden. the night before he was acting fine. Any ideas for what could cause this? i just feel the need to know.
the vet doesnt know as of now.

Sometimes the wound can be hard to find, but it sounds like an abscess secondary to a bite from another cat.
