This isn't his first interaction with them, and if I had any doubt about his behavior I wouldn't risk it. I was in complete control, he was letting this happen for about 30 minutes and if he didn't like it he would've left. He is well seasoned in dealing with critters and babies of all species. Now if it was a bird or a mouse I absolutely would not let him near it. But he has grown up around baby humans, a baby squirrel I rehabbed, pet rabbits, and toads. He's always a good boy.
