Well I got blue Carefresh bedding from Kmart. Moah and Shadow my pet hamsters are in the same tank. Shadow the Male hamster seems to be doing just fine. Moah is a female she's the one with patches on her lower back. I got her last March from the local Petshop so im not for sure how long they have had her. She's still very active and I have never seen her itch before but she mostly comes out at night. Another question I had was how long is a hamster supposed to stay in thier ball? (the ball that lets them run around on the Carpet)
Come to think about it she didn't start losing fur until I put them two together. At first they really hated each other too now they seem to be doing fine even sleep in the same Igloo. I really do not think its going to grow back because she's has had those patches during the start of fall. Thanks for the feedback and I appreciate the answer you gave me about the roller ball.
