1 cat inside.
I have a couple squirrels that come visit on occasion. Quite a few birds of course. I had 2 ducks - we named them Alice and Jasper. They came all the time but we've not seen them since May - they usually hang out in the summer, we're hoping to see them again in the spring. They actually knock on the sliding glass door when they land and let us know they are there. We feed them. Probably shouldn't but can't help it. They got quite use to us and would let me talk to them. I always have some water out for them too.
