My leopard gecko (I think it's a female but I'm not sure) keeps burrowing herself under things. It started with burrowing under her reptile carpet so I secured it, then under a heavy rock which I errorneously assumed was to get a hiding cricket, and then I got concerned when I heard her moving so I went to check and she had wedged herself under her very heavy water dish and I thought she was dead! Luckily she's OK but I keep hearing her digging all through the night and can't sleep because I'm afraid she'll hurt herself.
What should I do? I'm getting her a better, new cage soon but I don't know what to do in the meantime.
