also they don't ruin the carpet or scratch wood floors with thier claws. They don't ruin the furniture with teething or scratching. a $2 food supply can last a month and the calcium supplement you can use is about $8 and lasts for many months.

so you can feed em on $20 for half a year if you really needed to. (unless you want to get em pinkies of live fish) that costs just a little more.

just more things to throw in there :P
