Frankly, I don’t trust the cat in this video. Neither should the hamster. He may be thinking the cats are going to give him a treat. He needs to be less optimistic.
Our cat Henry never showed the slightest interest in our pet mice. But he’d sit and contemplate our baby fence lizards by the hour. Never caught him trying to open their tank and get at them, though.
That gray cat seemed more wary than the hamster. One hamster bite to the nose would probably be enough to discourage the cat for life. 🙂
