Your cat is so lucky that you rescued him! It sounds like he has a big personality and is smart, too

. I saw a big cat stalk our chickens yesterday, so I set out a trap last night, but didn't catch it. This cat comes around during the day and is in our yard all night (we catch it on security camera)

I chase it out of the yard, but now will have to leave our chickens in their coop until I can catch it. It's disheartening to think once I catch it more will come. Another problem is that few of our local shelters will take cats and they also will release them back into my neighborhood once they're spayed or neutered, so that's not helpful.
I love indoor cats, but the ones left to roam all day are a nuisance. After reading Peter Marra's _Cat Wars_, I also realize that they're causing the extinction of bird species worldwide (
