The substrate in my toads house in coconut bark shavings. However there are a couple potted plants in their house, and they're constantly going into the pot, digging up the roots and burrowing there in the moist potting soil.
My first question is, can this harm the toad because even the most basic potting soils have some plant fertilizer in it?
Secondly, how can I give the toads what they want and make them happy so that they will stop tearing up the roots of the potted plants to burrow there?
They've been doing this for months, and I know it means they want a moist place to hang out other than their water pond. Any suggestions? I'm wondering if I should just give them some more potting soil as a layer on one side of their house for them to enjoy, or if there's something else I should use to create this moist spot for them which they seek.
