My 130 pound sulcata has been acting a little sluggish recently. I have been keeping him in our shed (with a heater) because of his size. Then the weather started getting cold and thats when he started acting like that. I dont know if he was still cold or what but i started getting really concerned and i just brought him inside and put him in my wash room also with the heater. Is it normal for him to act like that because of the weather or is something wrong?? Please help
