I'm neutral on the whole idea. Though, I do have experience with the matter. My dog was never neutered, and...He had puppies with the neighboor's lemon beagle.... My dog is extremely mild and friendly, though, so to me, it doesn;t make a difference behavior-wise. x3 ~
I'm getting Renji neutered, of course, though. ~ Kiba
If he hasn't been around unaltered cats.. see if there is a breeder in your area or if anyone knows of a breeder in your area that will allow you two to visit their cattery. Make sure they're willing to take you to the "boys" room or area, so that your boyfriend can get a good whiff of it... if you're lucky, maybe you'll get there about the same time that a female is in a heat cycle.
