Last year when my cat was a kitten she had a reaction to one of her shots ( I think it was rabies). She had a lump on her neck at the injection site for a week or two. Now her shots are due again and she has a vet appointment tomorrow. I'm so worried when I read how some cats get cancer from those lumps. Our older cat died 1 1/2 years ago and it was so hard for my daughter and me ( we had our cat for over 18 years). I don't want anything to happen to this cat. Rabies is required here in PA but my cat is indoors. I know she may someday get out/escape so I hate to skip the shots.
