How cute! Simba looks so nonchalant about the ratties roaming around him....but I wouldn't trust him alone either! I had a border collie years back that adored little critters, and I'd alway's have a "TV" (it WAS entertainment behind glass) for her. She loved it when I'd put the rat, guinea piggy, whatever on the floor for her to babysit. I could leave a mouse with her, and she'd keep herding it to stay in one spot lol!
