Yep, you heard that right - potty train a bunny. This is actually a lot easier than you think - we use those little disposable chucks pads and have one area in the house where it sits. The bunny went potty a couple times and we moved it/the bunny to the potty mat. Two accidents in the beginning and she's gone potty on the mat ever since!
She's actually a pretty chill, snuggly pet - even when being tortured by a 6 year old, she doesn't seem to mind.
