You said it's a stray right? My advice, just because of my experience with strays, if you have a lot of mice or squirrels or chipmunks in your area, you might want to keep it around. That's what my family does. I mean now we have the Hawks and coyotes but before they settled in we used the feral cats. We usually just left milk in a plate out on our back porch everyday with a little bit of cat food. It wasn't uncommon to find them hiding under our porch when it was raining either.
