Our first alters came to us altered before 12 weeks, and we have followed the same routine of early altering. We live right outside Oklahoma City, so we had a large city and several smaller towns outside of it that were driving distance for us. It took many weeks calling just about every vet in the phone book, and finding out if they did early altering. Once we found a handful, we set up appointments to interview them. We had done research on anesthesia's and knew what we didn't want used, and what we did. When we found a vet who felt comfortable with altering, and also would listen to us as well, we had found our vet.
My beginning questions were answered on early altering in this website: http://www.winnfelinehealth.org/repo...ly-neuter.html
, and the additional questions I have had, I have emailed with a vet in Canada who was able to reassure me that I was making the best decision for myself and my kittens.
In just my experience, my kittens have a smaller incision, that heals quicker, and our babies are playing the same day they have surgery. They can heal in the comfort of home around Mom and littermates, and then when they go to their new home, that is one less thing the owner has to worry about.
I also want to say that there was one vet who changed his mind after reading and researching it himself, he seemed very nice, but we felt more comfortable going with someone who had the experience of early altering.
In my respectful opinion, if one can find a vet who will perform early altering, it should be done for many, many reasons, most of which are beneficial to the cat, but also the new owner as well.
I do know of a breeder who allows her kittens to go unaltered and she has a contract stating that the owner shows proof of s/n by 8 months old, or it is assumed the cat is being used for breeding and the person is sued for $1,000.
