My 9 year old beardie basically hasn't eaten anything for the past month. We offer him various veggies and fruits every day and crickets every three days (his usual feeding pattern), but he isn't interested. Last Wednesday we finally tried a pinkie, which he ate after some cajoling. Since then, he is again not interested in eating. He pooped a few days before eating the pinkie (not sure how, since he hadn't eaten in weeks), but hasn't since.
He is pretty lazy in general, but recently even more so - he probably wouldn't come out from under his stick if we didn't pick him up and move him. He has gone through similar periods in the past, but never for this long.
We have tried soaking him in warm water (every other day for the past week), but it hasn't seemed to help. Temps in his basking spot are ~100-110, and ~80-90 on the cool side.
Any advice?
