I couldn't help noticing that in the episode where the yellow-eyed demon showed Sam the night his mum died Sam's mum didn't say who are you but instead seemed like she knew exactly who it was. Does anyone know why because I can't find anything.

My cat has a wound on his tail and then above it a hole and the hole is really deep. I took him to the vet and she said that it's just from a fight and gave him a shot to help the healing. It's been a couple of weeks and his not getting better and his in pain, and his tail is really swollen. Please help I don't know what i'd do if something was really wrong with my cat and I didn't know just because the vet took one look and said fight.
