My one year old spayed mini lop Petunia is pretty good about using the litter box (mostly successful with peeing) when she’s roaming outside the cage. However, she apparently did not get the memo to use the litter box in her cage. We are constantly transferring her poops and rubbing her urine stained bedding into the cage litter box. We have her hay supply right next to the box and when she sits in it we give her the oxbow treats she loves. She’s clearly not adversed to her litter box. She sat on it for 10 minutes but when she got off she promptly pooped in her bedding! What do we do?! Why isn’t she getting the concept? What are we doing wrong?!
