My dwarf rabbit had two babies. They grew very fast and although I had planned to wean them at 8 weeks, decided to wean them at 7 weeks because they are so big that it was getting hard for mama to feed them. They have been weaned for about 1 week now, and since they left, the mama has been tearing her cage apart! She dumps out her litter box and just generally makes a huge mess. Is this normal? Is she going through some type of depression? She also doesn't want to be held. She will come to the door of the cage and wants to be pet, but she won't let me pick her up like she used to. And she doesn't come out to run around the house like she used to. Any thoughts?
