Hello! I have two bunnies (honey) is a female determined by vets. We recently got her a bunny friend who we also thought was female but we are now having second thoughts. (Bonbon) ever since we got bonbon we have kept them in two cages apart from eachother but in view of eachother. Honey has recently started pulling fur out and making a nest looking thing but they’ve never been together to mate and we thought bonbon was female. honey has also started making guinie pig honking sort of noises and thumping a lot when she is in the cage but she is fine when we take her out multiple times a day.. does anyone know what this might be because? Is she stressed and how do I fix it? Or is bonbon maybe a boy and she is making mating calls?
