My baby kitty, jack, has a lump at his vaccination site (shoulder area). He had his final kitten shots+rabies on January 5th. My vet said it could just be a reaction and should go down on it's own, but to bring him in if the lump was still present after 30 days. We noticed the lump a week or two after his shots and here we are approaching the 30 day mark and the stupid thing is still there. I am so worried about him and terrified it could be a tumor from the shots that I didn't really want him to have in the first place. I feel so guilty. I love my baby very much and hope and pray that this won't turn out to be bad. He is the sweetest kitty and I will be beside myself if anything happens to him.
