Hey!
I have a little 3 month old kitten I got from a rescue centre. He had his jab last Monday and we collected him last Tuesday evening, I didn't see anything obvious until a day or so later, but he seems to have developed a huge lump on his back where I think his jab was.
It moves and sort of feels like it might be water, I'm not sure. I called the vet and they said it was normal, but to monitor for a couple of weeks when it should go down.
Has anyone experienced this in their kitten before?
It's almost half the size of a golf ball!
