Hi @Anis
I’m so sorry you are going through this problem. 🙁 Spaying will definitely help, this could be her way of showing that this is her territory, since you moved, she might feel as though she needs to establish that. What could help is to pick up her poop and put it in her litter box so that she gets the message that that’s where she should go. Alas though, she is young, and youth in rabbits can sometimes blind you to the message that is being sent.
You said that her litter habits were good before this, so I don’t think that going through the litter training process will do anything, or teach her something she hasn’t already learned. How soon until her spay? Spaying will take away the sharp edges – but not right away, 4-6 weeks after spaying, they will go through a post-spay craze, where they have even stronger hormones than before. Afterwards, though, it leaves you with the most lovable bun you could ever ask for. 🙂 She is also adjusting to the new space, it is all foreign to her, so after she adjusts, and is spayed, it should come to an end, and she should resume her good litter habits.
It will be hard and require a LOT of patience, so I am wishing you strength as you endure it all! Wishing you a calm bun! 🙂
