I agree that a person's opinion is not "complete nonsense". Everyone is entitled to their opinions, and I'm sure everyone here does what's best for their cats and their situations. For me, growing up and seeing other people's outdoor cats suffering wasn't a really good influencer either. People's opinions and beliefs are shaped by what they see and how they've been brought up. It's still saddens me when I see dead cats in the road, be it stray or especially pets with collars on. For my cats, they don't have a desire to go out, so I'm not going to force them. They seem as happy as they possibly could. I'm not attacking people to have outdoor cats either. After all, I suppose in a way I have an "outdoor cat" which is a stray. I can tell she would rather be an indoor cat though. I don't know her history, but I know something bad had to have happened to her because her tail has a really bad break in it near the tip. I inquired with the vet about that when I took her in under the stray program, and he said that it probably doesn't hurt her anymore, but it looks really bad. Anyway, my point is, if your cats are happy inside, then leave them inside. If they're happy going in and out, that's fine, there's just a little more precaution to make, like Troy mentioned about finding a house that's cat friendly. Although I do favor enclosures to the outdoor life, but that's just my opinion.
