No other bunnies, just the 2 cats. I don’t want to banish him from the couch because that’s where he also crawls in my lap for snuggles. This morning it occurred to me that he thinks it’s a game. He’s been very playful lately, and he loves it when I chase him, he binkies away from me until he lets me “catch” him. Today I caught him on the couch just hanging out. When I said “Get down!” he did two binkies. It was actually really cute. I understand that he enjoys marking things, if it were up to him the whole house would be covered with pee. I guess I’ll just let him out of the cage for no more than 2 hours at a time, then put him back in for a break. I can’t think of anything else.

Hopefully spaying will help your bunnies’ behavior, but like I said it didn’t help with mine! You’re right, it is tiring. I’m definitely spending more money on paper towels and laundry!

If anything I think he thinks of the condo as a reward! I always get him to go in by giving him some pellets, maybe if I’m doing it right after he pees on the couch he thinks he’s being rewarded. It takes a couple minutes to do that so I didn’t think it was being linked in his brain but maybe it is. As long as he’s been out for at least an hour, he’ll sit and munch on hay in there without protesting.

I just thought of something else too, recently I caught one of my cats about to go in his condo, she was halfway in before I pulled her out. Mr. Bun-Bun saw that and bolted back to guard the door. Maybe since she tried to infiltrate territory that’s supposed to be his only, he amped up the aggression.

Oh and good point about him still being young too, I didn’t think of that. He has become a LOT more hyper recently, but that could be due to a combination of all the things I mentioned… who knows.

He’s basically litter-trained, but unfortunately thinks the entire couch is also his litterbox. Lately I’m not letting him get up there, he’ll jump up and I immediately scoop him in my lap, or shoo him off. He also frequently pees right in FRONT of one of his litterboxes (as well as in it.) I don’t know if I should break down and get another box? 3 for one level of the condo seems excessive!
I’m going to my parents’ house for a couple days, I’m hoping the change of routine will calm him down. He loves to run and binky in their house with all the carpeting, and never peed anywhere there (knock on wood.)
Lately his chasing the cats is a bigger problem. He has no backup plan, I don’t want the cats to turn on him (so far they haven’t, but they could?!?) He seriously lunges and chases them everywhere. He even lunged at my roommate the other day! He really just wants the apartment to be me and him only!

He definitely thinks the couch is a play area because I’ve caught him doing binkies up here before. But with the cats he’s being aggressive. When he first came here he would run around them in circles more playfully… that’s when my cat would swat his butt. Now he’s being aggressive because he’ll catch sight of a cat, perk his ears all intensely, then crouch along the ground with his ears flat and lunge towards them, then keep chasing them no matter where they run!
I think it’s more him coming into his personality because he’s comfortable. In his prior situation I know for a fact the girl provided him with exercise and good nutrition, but she was unwell and would have spells where she would stay in bed for days – literally – and he was in his little cage the whole time. Then when he was at the clinic I took care of him, but was only there 4 days a week, and at night he’d be in the dark in his little cage for 15 hours! Now he’s in bunny heaven even though he can’t be free range, he’s still spoiled and happy. I never saw him binky, sprint, toss his head, or flop until he had been here in my apartment for a couple weeks. And yeah I’m lucky, he definitely loves me!
His litterboxes are those plastic pans used in hospitals, big enough for him to sit in with room to spare.
