I used to use Rodent Pro but the last few times I did their feeders were kinda icky and reeked of urine. Their packaging wasn't as nice as Big Cheese or Perfect Prey either. Maybe they've gotten better. I wouldn't mind giving them another shot since they're one of the few suppliers that has rabbits, guinea pigs, hamsters, and quail as well as mice and chicks. I love giving my snakes a variety of prey items.
