My bunny Henrik is 1 on Wednesday, I got him when he was 8 weeks old and within a few days he was litter trained. I have recently made some changes to my house and his hutch and all stuff are now in a different room, he does not use his litter tray anymore and keeps pooing and weeing on my bed and the couch etc..... anyone got any advice or is he just marking his territory because of all the changes ?
