hm? cats need exercise too, if anything it's way more annoying because you have to either take them on walks where the cat spends half the time walking in a circle, and half the time wanting to sprint at full speed, or you have to get cat toys and make them run around for half an hour straight.

Just letting the cats go outdoors on their own is a bad idea for the same reason that doing so with dogs is a bad idea, they'll kill a tons of animals in the wild and will likely get hurt or even killed.

Especially in a world where most places have vehicles zooming along without a care in the world, it's extremely irresponsible to have outdoor cats.
