Hi my 18 month old horsfield has been sleeping a lot for the last 2 weeks and is barely eating. His basking area is set to 32 degrees, I have also replaced the UV bulb last week. I get him up every day to soak him and offer food, sometimes he eats a small amount, sometimes nothing then goes straight back to bed. Is there something I'm doing wrong? He is normally fairly active through the day and only goes into his bedroom around 6pm when he settles for the night. He normally eats most of what I give so this is out of character for him. He has also lost some weight. Can anyone give me any advice please?
