I had a stray neutered last Monday. After the neuter his tail has gone limp. He’s not holding it down himself. The base of the tail by the spine looks like it has muscle movement but the last 3/4 of the tail just dangles. The vet told me it’s because he is in pain and it will return to functioing but I think she thought I meant he was holding down on purpose. Vet is not back until Tuesday. It doesn’t look like he has any feeling on the part that is limp. I have had cats for a long time and have never seen this after a neuter. Anyone see this before?
