i have this horned lizard, and it appears to be sleeping lots. im wondering if its sick or not getting enough food. i try to feed it ants and bugs every day, its about 2 inches in length atm. whenever i look at it it seems to be sleeping, it has its eyes closed and i can handle it and itll often stay asleep. it will wake up for short periods though, to hunt bugs or to find somewhere else to sleep at. i keep it at room temperature, 75-80 degrees during the day, and it gets water, sometimes sleeping in the bowl. its color tends to range from tan to really light tan, and sometimes a dark muddy tan color.
is this normal behaviour or strange?
