We had a male and female. Had both fixed when they started spraying--that was the main reason. They were both strictly inside cats. Leash laws don't just apply to dogs, IMO. They were both extremely happy animals. We kept a good rope (not carpet) scratch post, and they used that. Didn't want them trained to scratch on carpet. Rope, to them, was preferable, so they just used it. No problems with scratching furniture. They both got fatter and more relaxed after "the fix". Didn't seem to bother them at all. Still hunted bugs that got in the house or whatever. Didn't change their personalities, just seemed to be more relaxed. Otherwise, we learned, their behaviour is very much influenced by those hormones. They seemed to stay as "themselves" all the time. I've never been a cat person, but these were very good pets. Even better than the dog. They knew how to be around, but stay out of the way, and knew just when was right to come around. They both died of kidney problems last year. Doubt we'll get any more, these seemed too much better than my regular opinion of cats.
