Actually, Monica, spaying them is VERY good for them. The males will not get in as many fights and won't get infections from bite injuries. They would also not be spraying or yowling as much, which could annoy your neighbors and cause problems for you. Spaying the females means they will not be as likely to get uterine, ovarian, or mamary cancer, especially if you get them fixed when they're young. And they won't be yowling as much, calling for boyfriends. Giving away kittens doesn't work very well. You're producing multiple liters of kittens per year, and each of those if cared for properly can live for 15 to 20 years, so you will quickly run out of adopters. And every kitten that you adopt out means a cat in a shelter that doesn't find a home. There's too many cats all ready; please don't add to the problem! Get them fixed!
