So, I have two female bunnies. One is a total angel the other one has a very strong attitude. Lately I have noticed that the trouble maker of the two has started digging through the litter box and creating a complete mess. Before I got the two I did a bunch of research and because of that I know that it is from boredom. I switched out some toys and she did not seem to care and kept digging. Any ideas of how to get her to stop digging in the litter box? I just need more ideas on how to keep her entertained so she does not make a mess constantly.
