one suggestion i will make is if you feed live. but a cheap tub for $3-$4 and make a setup with a small water dish and some hamster food. that way if there is a refusal you can house the food item properly to keep it healthy untill it is eaten, just because its food does not merrit letting it starve in some loansome tupperwear container. besides thats a waste. this is what i do. made a lil rat tub. has some aspen shavings in it, food, water and a little house made from a small plastic plan pot with a door cut in it.
