I know for sure all kinds of peppers are ok, and mine have had all three colors. They don’t seem to have a preference for any particular color but will eat them all. Mushrooms are not OK from what I’ve read, and I believe all oranges are OK; I’ve given the regular kind and mandarins. I’ve read on the house rabbit site that even the peel is OK. A breeder suggested to me that I give Kokanee black sunflower seeds to put weight on her… She’s done it before so I supposed they are OK too.
If he’s that terrified of the hoover, I would assume he’s quite upset. You could try little therapy sessions. I would start like this. Have him in a room with you, and the hoover. Turn it on quick and off quick. Give him a treat, tell him he’s good, let him out. Do that as much as you can/are able and increase the amount of time you leave it on as he tolerates it. That should get him to know that nothing bad is going to happen, in fact he gets a treat when it’s on. Funnily my Rupert is also terrified of the vaccum, but not bothered by it at all if he’s in his cage with the door closed. If it’s open or he’s loose, it’s very scary hehe.
I’m sooo jealous he’s sleeping in your room!! I’m working on Dave that Rupert can sleep in our room at night (Rupert cuz Dave likes him the best and he’s pretty non-destructive) but so far not so good. I’ll keep trying
