My kitten has a bump on the back of her neck that popped up today.. It isn't painful( i have squeezed it) and she is acting normal. It is kind of cyst-like, about the size of a nickel, I am just worried about the position (at the base of her skull where it meets her neck). She is already going to the vet on Tuesday for more shots, should I take her sooner? She is 16 weeks old. I googled it and couldn't find anything

Did this bump on kitty come after you had the first shots? if so it might be from that. and will go away in time. The same thing happened to my Cocker with his first shots. I called the vet and She said that it happens sometimes. and give it a few days and it did go away.
