Though you have to admit, being a pet (especially a cat or dog) must be a great life, especially if you're got decent owners.
No work, everyone tends to like you by default, free food and housing for life and various toys to play with. Arguably even more so for cats, given that their life comes down to 'do what they want' pretty much all the time.
But yeah, it must be a lot harder for non pet animals, and horrible for a lot of ones used as food too (especially in some modern conditions).
