When my cat has kittens, I'm going to put them in a bag and tie it shut.
That doesn't sound humane at all. Why are you going to do that to your cat?
I can do what I wan't I hate kittens.
I think it's very messed up for you to plan on suffocating your cat's kittens. It's never okay to purposely kill a living creature just for your amusement. Try to think very hard about what you're doing, and maybe just let someone else adopt those kittens for you?
I won't get a positive response from you.
If you don't want your cat to have kittens you should they them fixed. They even have free programs if you can't afford it. Also you can call a rescue to come get the kittens and they can find homes for them.
