I just noticed that my bunny Pepper made a nest in her bedroom. She has never done that before and I'm wondering what is going on. It's a big pile of fur that she obviously pulled. I got her from the SPCA about 1-1/2 years ago and was told she was spayed. Also, there is absolutely no chance she could have come in contact with an intact male bunny, so it must be a false pregnancy. Do female rabbits ever have false pregnancies even if they have been spayed?
