My buns are now liter trained (thanks to the help of a lot of people on this site after months of not working) and theyve been doing really good! But here recently they started pooping under things, like my desk, bed, dresser, beside table, etc. While theyre still using the majority of it in their litter box and thankfully not peeing, is there a way to train them to stop, or get them out of this habbit? It's like they know they shouldnt be cause its not on the floor in the open, only under stuff. Like an immediate cutoff ! Should I just block off things they can get under? Is that normal bunny behavior?
