bmulcahy,
Good job on scheduling a vet check. Whenever concerned about an animal, even if it’s nothing, you can’t go wrong by taking it to the vet. Better safe than sorry! It is however, not unusual to see similar symptoms from a brumating Uro. Even without an induced cooling period or even a shorter photoperiod, many Uros will go into a state of rest so to speak. I have two Mali’s that are not being cycled and they only come out for short periods of time during the day and eat very little. This also makes Uro defecations a bit of a rarity at this time. It could be that he is just doing what a Uro is programmed to do, but like I said earlier, a vet visit is the safest and best choice! Also, age, his pre existing health and his environment play a good role in determining if it’s a sick uro or a brumating uro. Hope this helps!
