But by that logic, you shouldn't let your kids go outside and play, either.
1. Kids are more intelligent than cats. Not always greatly more intelligent (I did some dumb stuff as a kid...), but still, animals have no clue what is and isn't dangerous for them. Kids you can at least supervise them staying in the playground or the backyard. (I've tried supervising a cat to stay in the backyard. Doesn't work, unless you have a high fence.)
For instance, the other day, I saw a cat very slowly walk across one part of the road... then leisurely sit and get all comfy right smack in the middle of the road. It wasn't until a car went by on the side the cat just left that the cat finally got scared and ran across the rest of the road... and I can tell you that if the car had gone by on the other side instead, one of my neighbors would be minus one cat.
2. Kids have to go outside at some point to live their lives. Cats don't (except snug in a cat carrier to and fro the vet).
3. There are some places out there dangerous enough to kids that parents *don't* let their kids play outside. And since there is a lot more dangers out there to a cat, the same principle applies. If it's a choice between disease, fleas, ticks, becoming roadkill, getting killed by sickos, etc. just so they can run around, pounce things, and lounge... or staying in a nice, safe, clean house where they can *also* (if you set up your house right) run around, pounce things, and lounge... why let the cats outside?
*You* know what's safer, so the animals that don't (and just think, "Ooh, outdoors, shiny!") need you to look after them.
After all, my cat *thinks* he wants to go outside. Then, on the rare occasions he does manage to sneak out on me, he immediately panics and tries running back inside (and generally goes to the wrong door, sigh). Of course, cats being what they are, he generally forgets he didn't enjoy his last excursion and tries sneaking out again... only to be unhappy again if he finally does. An animal wanting to go outside really doesn't mean anything.
