Lily is a 3 year old Netherlands dwarf I’ve had since he was only a couple months old. We already went through the fun adventure of marking and getting neutered when he was a year old. He was litter trained for the most part the following years. Summer of 2016 he got an ear infection and had head tilt for a month but he is back to normal now. It was about this time last year that he forgot how to use his box and I’ve been trying every method to retrain him. I am not sure what set him off from litter training considering I’ve used the same carefresh natural bedding, Timothy hay from our local feed shop, oxbow food, and regular veggies with some treats here and there. He’s always lived in my room as a free roam bunny and likes to sleep at the foot of my bed in a little bed of his own. Since he has regressed I have had to bring his old hutch back up and stick him in it because I don’t have any better way to keep him secure. I try to let him out as much as possible but he always poops all over the place and if I leave him out overnight he pees on my bed! So unfortunately he has been stuck in his cage which is about 3 feet long, a foot wide and two feet high. I hate having him stuck in there because I know he is unhappy but I can’t let him out because he just makes a mess. The old method used to work where I have a “kitchen” for him so his butt has to be in the litter box if he wants to get to his food, water or hay but this is no longer working. He is mostly pooping and peeing in there but when I wake up there is usually and handful of poops where he lays down. I made him a little play pen out of C&C squares which is not honestly as big as I want it but it’s big enough for me to sit in there and him to run around a little (probably 5×5 to 7×7 Area). But I have discovered even with 3 litter boxes (1 in the cage and 2 in play pen) he is still refusing despite me scooping any poops into the box. He has his favorite bed in there and he likes to pee on it so I’ve just given up on having that in there until he is litter trained (he used to never pee in it but maybe poop a little sometimes). Anyway, he’s been stuck in his cage for a past two days and I’ve been trying to clean up after him and move poops into the litter box and when he is in the little box to poop or pee I give him praise and treats. However he is a very grumpy bunny and always grunts and nudges at me for picking his poops up to put them in the litter box. He never has been one to like pets or being held and I respect that and generally just let him do his own thing but I’m trying to bond with him and gain his trust. I’m just not sure what to do! Some people say scoop the poops into the litter box and put the bunny in the box but I feel like me reaching around in there and moving him to his box is just making things so much worse! He was super easy to train the first time around but this time I’m just not sure what went wrong. I understand he won’t be perfect at this litter thing but he is peeing and pooping everywhere! I don’t mind having to scoop up his poops here and there, I just want to not have to lock him up in this cage anymore. Thank you for your time!
