So I just put a rat Fuzzy I'n and he took it first try I ha the guy at the reptile store rub a mouse on it. I chose rat fuzzy ove rat pup because I saw the size of there rat pups and they were huge so I'm planning on fuzzys till I can use pups
After 2 or 3 meals with fuzzies, switch to rat pups, trust me, he'll be able to take it.
