More items are unlocked as you play through the game. Items in the shop do vary at times so make sure to keep checking back to see if anything new has been unlocked and is available.

charge your ds in, go to the two hamsterz that are partners ( put two hamsterz in one cage and click the heart if u don't already have a partnered hamster) leave the ds on for 2 days and 2 nights NOT on sleep mode ;D and make sure that u have a full up water and food and some toys and u will get TONSSS of money $$$$$$ like 100,000 mabey more if you have lots of things the hamster can play with but your hamsterz WILL get sick (u will have to buy pills to make it better ;D) hope this helped ~_~ rosebud9797 ;D
Buy a new cage and go to your hamsterz current cage. Then drag the new cage up to where you see another cage pic. (all stuff currently in cage will be moved to inventory)
