Cat lumps and vaccines - Answered by Dr. Van Lienden

[krdahmer]

I noticed the other day that Fagan my cat (the new little orange fella) has a small lump on the back of his neck, pretty much exactly where the vet gave him his first booster shots last Friday. Since I just noticed it, I'm not sure if it is getting smaller or larger... it does not seem to bother him if I touch it, so what I'm wondering is should I wait a few more days and see if it goes down? Could it just be a small bruise from where she had to pinch his skin? I don't see anything that would lead me to believe that it was an infection... he's not scratching, there is no visible redness, etc. What do you think? Anyone else ever had this after going for shots?
