I just recently purchased a male and female holland lop 6 days ago, both from the same littler they are about 10 or 11 weeks old. Iv noticed almost right away after bringing them home the male has been peeing on and trying to constantly mount and hump the female, she does not seem to enjoy this and runs away for the most part. I do have them in separate cages but let them out together supervised so they can bond, play and have fun. I just stop him from humping her when I see behavior begin to occur at this point, which is almost every time I let them out together. He will begin to Honking and chasing her around until he gets his hump in. Iv done a fair amount of research being curious.. enough to know what this most likely means. I have already called and scheduled a visit with my vet when I got them and discussing having them both neutered but must wait as they are both too young for that at this time from what the vet told me. I'm new to this and honestly just need advice until I can get them both neutered, should I be letting them out to play together even though he just wants to mount most of the time? Am I right in stopping him from humping her? I want him to hump a toy or anything else but he only seems into her. Iv been putting stuffed animals in his cage but he does not seeming to be interested in anything other then her. Would it help if I kept there cages in separate rooms? Would that help keep his mind off her, because as of right now they live in the same room just separate. I am also curious if I allow him no ability to mount her will he eventually get so frustrated he will just begin to mount any toy I leave around him or become aggressive towards her and just reject the toys regardless? Any advice would be apricated.
