Petsmart was having a pet halloween costume contest. I made Snickers (my hammy) a lady bug costume. Don't worry, it's loose on her so she's not being hurt. : )
EDIT: Since may people have been asking, I made the costumes. Here is how: I cut a circle out of craft foam and added the details with other foam. There is a piece of elastic that is attached underneath. The hammy slips through that part. : D It doesn't stay on for long due to their bodies. You also want to keep it very light for them to wear.
