There are many ways you can keep your hamster healthy. Start by feeding him a balanced diet. Buy a brand of hamster food that will take care of his daily nutritional requirements. Supplement his daily diet with a moderate amount of greens. Be sure that your hamster always has a fresh supply of food and water. His bedding should be changed and his housing washed regularly.

Choosing the housing for your hamster is an important decision. The general rule of thumb is to get as big a cage as you can possibly afford. Keep in mind that the hamster cage may look big when you first buy it in comparison to your hamster, but after you've put in a food bowl, toys and an exercise wheel, it will start to look pretty cramped. Hamsters that don't get enough exercise can develop cage paralysis (see General Hamster Care for more details).
