I don't have any myself but I am fascinated with them! They're closely related to chinchillas, I think they look like a rat/chinchilla. VERY cute! Search around for some pics on here, I know we have some degu owners around!
Degus are very cute and are very easy to get along with.I have several but haven't gotten any recent pics of them.
They make different sounds which I think is very cute.Mine are all very friendly and love to climb out onto my hand.
Although degu are related to chinchillas to me they look nothing like them. They are way smaller and do not have the soft, dense fur. To me they look just like a large gerbil But are much much more vocal.
