Welcome, she is adorable
binkies are good… it means she’s happy!
Holding a rabbit in their litter box won’t help them learn – you have to use their own instincts to your advantage. Rabbits are prey animals, so they like to keep their waste in one spot. Some tips on helping her learn her litter box:
If she has a cage, don’t put bedding down in the whole thing. Just put bedding in the litter box.
If she is going in a spot all the time instead of her box, move the litter box to that spot. You have to go with what she wants, not her with what you want.
Get a cat litter box. The corner ones they sell for rabbits are too small for most rabbits to like to use. (several if she’s not in a cage)
Keep her hay in her litter box rather than out, they like to eat and poo at the same time. So you’ll get more droppings out of the box if her hay isn’t in there.
Keep her confined to the smaller area until she learns.
Clean up any accidents with vinegar and water to avoid her remarking the area.
Some rabbits won’t litter train until after they are altered as well, hormones can cause them to mark territory. If she doesn’t train, she’ll probably get there after she is spayed. Another reason to have her spayed is females have about an 80% chance to get cancer by age 2. It can also help with aggression and any destructive habits she may start once her hormones kick in.
