Thanks for replying! I don't really have anyone to hold her for me so I can slip the card in and bug at the right time, but she's smaller than my thumb, I'm scared to rip the skin of her lip trying to wedge the card in. Are they very delicate or tend to keep their mouths open for a moment when pried?
She did show interest earlier in the week in a dubia, no running after anything but really she tried to get it and sadly got dirt instead. Otherwise she doesn't respond unless something bumps into her and she withdraws her eyes. However she's always watching me back when I check on her so I can't say if she hunts while I'm gone. She spent about three or four days fully burrowed a couple days ago, but she had strength to snap at my finger when I accidentally bumped her nose checking the soil and then hop around her tank angrily until she found a new burrow. She's up today, after being moved the other night. Hopefully she'll stay up tonight so she can see the new food.

I use tap water treated with Tetrafuana aqua safe for reptiles and frogs.

Heading to the store for crickets right now, I will check if they have reptaboost, if I can I will get it. Otherwise I'll wait on that and try feeding dusted bugs unless it gets worse by payday.
