What a beautiful kitty Marble is - aren't they all though. I don't expect you to know the answer, but I bet it is too much to hope for that when the kitties were abandoned at the vet they had the sense to have the mother sterilized... As a volunteer for 4 animal shelters I have to say that I am sick and tired of the number of cats and dogs being dumped at our doors. Sterilization must be made mandatory to get this under control - one day...
