What this boils down to is, you shouldn't keep an animal in your house. That is why I'm against pets too. This is done to horses and various other animals too - horses can get really violent when "unfixed". Do horses and cats and dogs have a choice in this matter? Nope. I suppose this is an old argument, and a pointless one. Until human in general learn to leave nature in nature, this will ALWAYS be a problem.
How would all the woman advocates on this thread like to have their reproductive tracts removed so that they would be more "docile"? Would that be right? Would you neuter your own children? Cats are mammals too, and they feel stuff, although admittedy sex is no fun for kitty.
This still doesn't make it right to leave kitty unneutered so he can go make 10,000,000 other kitties. Get a vasectomy at least, geesh.
Perhaps you COULD move into the "world" of the feral cat. Check out empty lots, abandoned buildings, and dumpsters behind restaurants. There you could experience the "joy" of the unneutered, unfettered feral feline.
I'm strongly against domestication of any animal - I believe it is an animal's right to be free. We cannot have double standards when it comes to the freedom of our children and the freedom of the animals we share this world with.
Yes, it's not fun for cats to have sex, but the only reason there are feral cat colonies is purely because we domesticated them in the first place. I personally would never force bondage on any animal - I wouldn't be able to stand the bad feelings etc.
If you have known what it is like to be absolutely controlled and caged in, then you will appreciate freedom the way I do. This is a significant part of my world view.
It is simply sad that this sort of procedure has to be performed in order to control our feline friends. How I wish that we never domesticated cats in the first place. But sadly, history cannot be undone. Maybe one day with the advent of cyber furry friends there will no longer be a need for this sort of thing, and then everybody will be happy, but up until that point, I will never have an animal of any sort in my home.
