So glad you got Elvis neutered and glad he is doing well. I had Ricky done in January of this year and the only problem we had was weight gain. It has been so difficult to keep his weight down since the surgery. The Vet said that males tend to gain weight after being neutered due to a change in their metabolism so keep an eye on his food intake. Ricky thinks he is being punished because he gets no more treats but I don't want to lose him due to heart problems because of his weight.
