If your bunny isn’t neutered/spayed (is it a he or a she? you only say it) they won’t stick to litter training. Hormones make litter training next to impossible. What have you done to try to litter train them?

Again, she’s not spayed and still pretty young. She won’t really take to litter training too well until she’s been spayed. But in the meantime you can keep her hay and food dishes next to her litter box because most bunnies eat and poop at the same time. You can also try to keep her water near there too. Continue what you are doing with the wiping up of the pee and putting it in her box, and scooping the poops and putting them in her box. If you notice she’s about to pee outside the box, you can gently nudge her towards it. If you notice she pees in one corner (most bunnies find one corner and pick that) you can keep the box there. For some bunnies it may be necessary to have two boxes. But for the most part, it won’t get a whole ton better for a little bit. Honestly, like everything else with bunnies, litter training is all about patience. Some bunnies just take longer than others.

The small amount of pee definitely sounds like hormones. If she’s less than 3 months old it’s also possible she was incorrectly sexed and she could be a male. Baby bunnies are often mis-sexed because they look similar down there until testicles drop. But the fact that she’s spraying so young makes me think she could possibly be a male because males usually mature quicker than girls.

You can try to have her on hardwood, but most bunnies don’t like it. It makes them slip and slide to much and it makes them rather nervous.
