well, right now i'm keeping my hammy in a 10 gallon aquarium. i guess, if i really had to, i'd buy a bigger cage for something else. but while i was begging my parents to let me get a hamster, it seemed that it would help if i didn't have to spend too much, you know? if i bought a bigger cage, i would have had to spend about $20 more, since we already had the 10 gallon lying around with nothing in it. i know that all little critters have different personalities. and not all the little ones bite, lucy. my hammy doesn't bite at all. but he's very, very, very uninterested in everything, and lazy. so when i place my hand in the cage for him to climb on, he just lumbers over, sees if i have a snack, if i do, he takes it and lumbers(not runs, he's not scared) back to his "lair"(what i call the big pile of tissues, poo, and food in his house. he's like a little dragon, except with a lot less sense of value), and nibbles a little, then drops it like he has short term memory loss, and goes todo something else, like run on ihs wheel, or eat more, or sleep. if i don't have a snack, he goes back, and i swear i can hear him grumbling "waste of my time...*mumble, mumble*"....like i said, he's very laid back.
