"is it inhumane not to let a cat out of the house that wants out?"
It is inhumane to let your cat out so it can catch diseases from feral cats (that you can catch too), get pregnant from a feral cat, get run over by cars, get killed by dogs, get killed and eaten by predators.
Here's a few diseases you can catch from your cats when you let them outside:
Cat scratch disease.
Roundworms.
Toxoplasmosis.
Rabies.
Campylobacteriosis.
Salmonellosis.
Cryptosporidiosis.
Giardiasis
You can also get ring worms, jock itch and athlete's foot (all caused by the same fungus) from cat crap. I had a bad bout of ringworms on my legs and jock itch last year that I got from sitting on the ground while working on my fence. I got rid of the ringworms on real quick by just by just sitting in the sun with shorts on but had go see a skin doc to get rid of the jock itch. I also got the Giardiasis parasite.
You live in such a lovely place.
Yeah, I know- probably most of those are here too.
