Awwww....poor little Mitzi girl.

I'm glad you got her all cleaned up and to the vet already. Peanut had a big cyst like that in the middle of her back one time. I, too, was amazed at all the pus the vet squeezed out - eewwww! How old is Mitzi now? The vet said these cysts aren't uncommon in older kitties because they just don't clean as well as they used to, and they're not as nimble as they used to be so they can't get to all the spots they used to. Peanut was 17 when she had hers. Somehow I don't think Mitzi's that old yet though.

Gently hugs and smoochies for the little queenie girl.
