The commonest wild animals in my again yard are opossums. I rescued two child possums as soon as when their mom carried them to my yard and left them. The mother possum got here into my house via the cat door I had at the time. She didn’t seem to be dangerous to tne cats (or they to her). I no longer have the again door with the cat flap, but my two cats exit, and several other strays (also fed by neighbors) come to look for meals.
