Just postponed spay appt for Abigail for 1 1/2 month. She is a lionhead, 6 months old, but only weighs 869 grams. Vet said that is pretty light. She weighs less than our guinea pigs. Our other lionhead, Dutchess, is much older and weighs closeto 5 lbs, already fixed. Does anyone have experience getting very small females neutered?
