Background: A friend just had a litter, and I adopted two. They were born on 4Dec, and I brought them home last monday. I understand that’s quite early, but they were already weaned and eating well, and they settled in really quickly. They’re relaxed and tame (eating and drinking well, flops, binkies, approach humans who enter their pen).

Their pen is in the kitchen (away from the stove!), next to the bathroom, and is about 2m x 1m. They have a cardboard box to hide in, a litterbox with a tray of hay (which is constantly refilled), and a shallow dish of water.

Problem: They poo and pee all over their pen EXCEPT in their cardboard box (that includes in their litter tray). When I let them run around the house (supervised play time), they pee and poo everywhere too.

I heard that rabbits choose one place to pee, but they’re peeing EVERYWHERE. I also heard they poop all over their cages to mark it as their own, but they’re pooping EVERYWHERE. Like, indiscriminately.

I’ve tried wiping the areas they pee with vinegar, but it doesn’t help. I’ve placed their pee and poo back in their litter box and showed them. No change either.

It’s only been six days since I got them, and they’re very young, so I guess that might contribute. Originally I was expecting to adopt adult rabbits who were already toilet trained from a shelter, so I’m pretty unprepared for this :/

How can I toilet train them?
