I can't believe that a simple issue like fixing yor cat can really show such moral differences. Its pretty darn shocking to me actually. I personal do believe in spaying and neutering personal animals. My current cat was a neighborhood stray and a neighborhood whore. The previous owner couldn't take care of her so he tossed her to the curb. She gave birth to two litters out on the street most of which died or were seized but animal control. I finally got frustrated with seeing the lack of concern about her so I got her to trust me and took her in pregnant again. The biggest problem I had was the fact as soon as she gave birth she would get out and pregnant again. Getting people to take them became an impossible task. I tryed hard to keep her inside. Burns would be able to answer this better then me but I was told that when a a cat is in heat that it is actually painful for them not to mate. Like a form of torture. So that leaves a dilemma. Allow them to mate and overpopulate, send they babies to the animal control and have them put to sleep, don't let your cat mate and cause them discomfort, or have them fixed. (Having had a male cat also whom I had fixed has its own set of problems also.) I opt to have them fixed. I personally wouldn't do anything to my cat that I wouldn't have done to myself. The surgery is by far more humane then alot of other alternatives. And in my cat's case she seems almost relieved not having to deal with the drive to have to mate.
