1. All Items cheat- Go to the main menu and it says start or continue. Press start and say no. Do this 5 times. Than press continue. Go to outing and press open cage. Say no than try again and say yes. when you are there, click on the brush and stroke 2 times. Than go back to cage and click on food, toys, Care and pattern and you will have all of the items.(This may take up to a multiple of tries to get the timing right, but it really works.)
2. Unlimited mini games cheat- (you must have pellets to do this.) Go to the cage and feed your hamster pellets. Than go to outing and than go back and your hamster will automatically want to play with you. Keep doing this and you will get lots of items and prizes
It is possible to have 6 of them; 5 with Hammy and one out. This is useful because the more Hamsterz you have the more you can go to the bedroom and get presents which means that you will get bigger cages quicker.
