Hello all!
I’m a newbie here, so I apologize if this question is in the wrong place!
A couple months ago, I adopted a lionhead bunny (named Elvis for his fabulous black hair!) who is completely blind in one eye and almost blind in the other. Despite his vision problems, he’s been doing remarkably well- he’s memorized the layout of his room, and he knows the sound of his food bags/boxes being opened very well! 
However, some aspects of his habitat- namely his toys- he is just not interested in at all. I can’t say I blame him, given his vision problems! He’s generally just much more lethargic than my previous bunny, and I’m a little worried about the impacts it could have on some aspects of his health (particularly his weight and his teeth- he never chews on the wooden toys he has!)
If anyone has any suggestions on how to get him more active and curious, I would be super appreciative!
