If you let your cat outside in the Americas (or anywhere cats haven’t lived for thousands of years) unsupervised I’m going to assume one of the following is true: you don’t care if your cat dies, and/or you don’t care about wildlife. Even if you live in a place with zero predators, why the hell are you trusting a CAT with road safety?
Saying this as someone who grew up with parents that let our cats live (and die, a lot) that way. And as someone who has seen two friends lose cats to coyotes in the past year. And also interrupted an attack on someone’s pet by a coyote. It’s been a bad fucking year here for coyotes.
