That sounds stressful for both of you. Can you get him a partner to bond to? Bunnies do better in bonds as it keep them company when you are gone.

That does sound pretty bad. I agree that a second bun might be better for him, but that would mean you need to get both buns fixed and wait till their hormones die down, and then go through a prebonding and bonding process while keeping them separate…which I’m not sure if you are able to since you’re in school.

Your profile indicated that he is about 4 months old, which means this is about the right time for him to hit puberty. I’m assuming he’s not neutered yet so I’m wondering if it could be his hormones acting up instead of separation anxiety. Has he only been doing these things recently or has he been this way ever since you got him?

I’m sorry to hear you and your bun bun are going through this.

Wick’s separation anxiety with me hasn’t stopped, but it has decreased in how distressed it makes him. I’ve done a lot of things, like keeping the TV on low volume when I’m not there (usually to a channel that I usually watch when I’m home). My reasoning is it breaks the silence in the environment so he’s more at ease when I’, not there. I also try and make my plans occur between 8AM to 3PM, which is when he’s usually sleeping anyways. I think it was also helpful that Wick found his comfort spots. For him, he likes perching on something high, like a dresser or the top two floors of his indoor hutch. So even if I am home, he will go to those spots to sleep, digest, relax, etc. without me, which makes me happy that he feels comfortable going away from me. That being said, he still lingers by the door in the afternoon to wait for me, but now he just chooses to lounge there rather than excessively peeing there or nipping his other parent. Other things that helped were to get him stuff to keep him occupied while I’m gone. Feeding his pellets through a windmill toy so it takes longer for him to get it, giving him a multitude of hay stations to keep him moving and busy…

All this being said, to your situation, screaming is a very startling reaction. Objectively, how much time do you have with him on average, and outside you, does he have interactions with anyone else regularly?
