My teddy bear hamster escaped about a month ago do to a faulty cage. We recently found him outside in our rabbits' pen, which is very close to the door. We assumed he got out through the door and made it to their pin because it's full of burrows. We recently found him out there-- he had been eating their food and gained a lot of weight. Can't tell you how cute it was to see him out there!
But anyway, I noticed he no longer seems to have testicles when I picked him up. Before he was lost, he had prominent testicles like most male hamsters. He seems perfectly healthy, and he is still excreting properly, but this part of him just seems to be missing. After using Google, it has said that it's something hamsters do depending on the temperature of their environment, but I'm skeptical.
