I never remove my hides. My BPs have learned that the sound of the hair dryer is the dinner bell (to warm after thawing). The ones that want to eat are typically front and center in the rack before I even open the first tub.
same with me. As soon as i take the water dish out, by the time i take the dish to the bathroom to spill the water thats in there, i come back and his head is out his hide.
It seems most BP's whenever you feed if u do one specific thing that u dont usually do, they eventually catch on...
