Yeah, I used to be that cat. Sleeping under a bush, drinking out of a puddle, until I found the perfect patsy.
Yes, I mean our human. After all, spending my day sleeping on her pillow is much nicer than dozing under a bush with one eye open. Except for the neutering, the Advantage drops and the worm pills, I'd much rather be inside.
(Feral or someone's pet who likes the food? I don't know. What I do know is that there is some trapping, neuter/spaying and a rabies vaccine in someone's very near future.)
