That soon? that is excellent Smudge and takes a bit of worry off my mind. I thought it was going to take weeks, did you get them chipped at all or is this if your going to bring them back? I might go and check things out at my local vet, my cat has been relatively healthy over the years, never had to see a vet except once when she was doctored. She is very timid and never goes out so is not exposed to other cats!
Thanks again
Linda
