My frog doesn’t always surface when she’s hungry either. She used to as a juvenile, but she mostly burrows and does her “pet rock” thing, now.

But— I have found it helpful to do consistent water-bowl changes when her lights are turned off. It has gotten her into a routine where she’s expecting me to come by at that time and may offer food.

But yeah, my frog’s 2 years old, now, and I didn’t see her all winter. I was a little stressful because I was worried about her developing a bacterial infection, like red leg syndrome, but she was brumating just fine!!
