Well I can give you some enrichment things that you could try to see if they work. For inside their cage, if you don’t have something like this already, you could put a dig box in, I use bedding and Pom Poms but you can use fleece rocks and other things. I got Remi a snuffle mat and she seemed to like that, you could probably find one in a pet store or online. Another thing is a fleece forest, hard to explain but you can look it up, it’s a piece of fleece that you cut at the bottom and draw it like a curtain for 5hem to walk through. Also maybe you could change the toy options to see if the like any of that. For outside your cage, you can hog proof a room and let them run around and explore. I use card board to block off spaces. When I let her out I usually put some extra toys that don’t go into her enclosure. She likes to attack empty shoes and hide under hats, I also have a long pipe that doesn’t fit comfortably in her cage. New foods sounds and smells are also good enrichment. Play some music for them or introduce new safe foods to them! There’s a bunch of enrichment threads on here if you look I bet you could find some more stuff! I hope this helped and their behavior gets better!
