Probably the most important thing about this whole subject is the fact that you are being a responsible pet owner and fixing them. So many people get them and then say they can't afford the surgery. Then their pets just keep reproducing. I admire the ones that fix their drop offs and strays and to all who adopt. Kudos to you! My DD has a friend whose outdoor cat is on her 4th or 5th litter. They always have some excuse.
