Is pine straw bad for hermit crabs?

Pine straw can be problematic for hermit crabs due to its acidity and potential for sharp edges, which could harm their delicate bodies. Additionally, the resin from pine needles may not be suitable for their environment and can cause respiratory issues. It's generally better to use other substrates like coconut fiber, sand, or leaf litter that are safer and more beneficial for hermit crabs. Always ensure their habitat is optimal for their health and well-being.
