Indoor vs Outdoor cat - Why are there more "house" cats now?

Good point, Nakhash! When I was young, some 40 years ago, there were dogs, cats and kids outside all the time. To quote a famous line from The Wonder Years: Back then a kid could take a walk without being afraid of ending up with his picture on the back of a milk carton. These days you can't just let your kids play outside unsupervised. And although it's the law (at least it is here) that you can't let your dogs roam around outside, even if it weren't, I wouldn't let my dog roam free in the neighborhood. I did as a kid with no problem. These days I'd be afraid someone would snatch up my poodle. My sister almost had her Brussell Griffon stolen right in front of her house. She had him out there with her while she was gargening. He was up near the curb and a car pulled over and the passenger opened their door and called the dog. I guess they didn't see my sister bent over in the garden. She heard them try to call over her dog and yelled at them. They just took off. It's a scary world we live in these days. You can't be too careful.
