Any major city or suburb. Almost any. It's considered a uncontrolled non livestock animal. I've never lived somewhere that it's legal but ya, I'm sure ...somewhere...it is. It will always be a jerk move though.

Letting your cat outside onto others property is illegal. Op could actually be fined or worse charged.

I know y'all love cats but fyi, in most places outdoor animals including cats are illegal. They are also terrible for the ecosystem.

A good owner can have a happy indoor cat.
