Meet Hamtaro, a 7-month-old dwarf hamster, who was diagnosed with diabetes in March 2003. Hamtaro is now on a low-fat diet and receives insulin injections once a day. He is gray, weighs 1.5 ounces, and has a sporty black stripe down his back. Hamtaro is gentle, curious, and loving. Despite his daily injections, he never bites and is always friendly and inquisitive.
