Ooh! Another thing! You know those rawhide chips that are hanging on the front of the first aisle in petcetera? I buy those for the rats, and they love them! But I would recommend them even more for a gerbil...they chew like crazy! Chibi_star put in the bottom of a pop can to use as a dish, and her gerbils ate almost the whole thing! Plus they ate most of their plastic dish, and you know those coconuts that they sleep in? Yeah, they ate it lol. So get the rawhide, it will be worth it! they are only like $3.41 for a whole bag or something like that Can't remember...
