Yes, I agree that you should talk to your vet about this. I have three males and they were all neutered before I got them. I was told that Sunny was neutered at 6 months and Pepper was done at 8 weeks of age. I'm not sure when Storm was done. So far they are all fine and none of them have ever tried to spray. I've also heard that if a kitten doesn't weigh enough then they won't do it until they've gained enough weight. I guess they're afraid of them not coming out of the anesthesia. Good luck and please keep us posted. I'm so glad that you got your cat a playmate.
