• Now that you know which type of hamster you want, you are ready to go out and find one. However, it is a good idea to have everything set up before you make your purchase. If you need information on how to set up a cage, check out Mahalo's How to Take Care of a Hamster page.

• Hamsters are widely available, so it is important that you look at several locations rather than making a spontaneous purchase. There are three places you can find hamsters:

1. Pet stores.
2. Private owners or breeders.
3. Animal shelters.

• If you are selecting a hamster from a pet store, breeder or private owner, it is a good idea to evaluating the other animals in the store as well as the hamster you are consider purchasing. Here are some things to look for:

1. Do the other animals look healthy? Any sick animals can indicate less than optimal conditions that could affect your hamster.Hamsterific.com: Selecting that New Addition to Your Family
2. Take a close look at all the hamsters the store or owner has. If any of them show signs of illness, do not purchase a hamster from that place. The hamster you select could already be exposed but not showing signs of the illness yet.Hamsterific.com: Selecting that New Addition to Your Family
3. Are things clean and in good order? If they don't take care of their surroundings, chances are they don't take care of their pets either.

• Many animal shelters offer hamsters for adoption. This is a good option because you will be rescuing an abandoned animal. Also, shelters will have access to knowledgeable people who will help you select a pet that is healthy and a good for your family.California Hamster Association: Buying a Hamster: Buyer Beware Don't think that you will be forced to adopt an older hamster. Shelters receive younger hamsters. You can browse a few of the animal shelters online:
