My female, Obi, used to eat in her water dish, minimizing her eating the jungle bark substrate I use. However, lately, she wants to eat in her "hole" and she sucks in a lot of bark. Most of the time she spits it back out, but she has to be ingesting some of it, and I am getting worried about impaction. I would like to know what other owners of ABFs use, and good and bad things about their choice. Thanks everyone!!
