You are correct in that I don't understand the point you're trying to make. This is what I originally said about kids

I mean getting a cat is selfish to begin with since you are getting yourself a pet after all, but as a pet owner you’re supposed to take as good care of them as possible. It’s like with kids. Once you’ve made the decision to get one you’re responsible for it and it would be silly to expect a small child to make the decisions. You’re the one who is responsible for their well-being.

You are responsible for their well being. You wouldn't let a small child roam freely outside without supervision. That would be irresponsible. It's the same with a cat.

If your kid never leaves the house then they will not die in a road traffic accident. I can’t put it more simply than that.

I have no idea what this has to do with the discussion or the point about kids. I wasn't talking about never leaving the house. I talked about roaming around freely without supervision.
