Hello I have a Russian Tort and have had him for about 3 months now and the past week he has been super sleepy and isn't waking up to eat as usual I have been waking him up to eat in the morning and he plays and will stay awake but as soon as he's is back in his house he burrows and goes rite back to sleep is this normal? Should I wake him at all? The temperatures in his house terrarium are 90-95 one side and 70-75 the other side overnight temp is anywhere from 60-66 degrees. I do live in Colorado and we are going into fall the days have been colder the last week also.
