Mouse has been sleeping loads for a good few years. The past few months Boo's sleeping has increased notably. She seems fine, she still plays in her digging box, is the same weight, loves us like usual & wakes in a nano second when you put food in front of her nose. Poor Joey looks bored in the evening. He isn't much of a doer (never really engages with toys or activities like Boo will) - he certainly doesn't seem to need or want more sleep. I do think he just used to like hanging out in the open each evening with Boo, not doing much but at least being awake.

what do you know about older bunnies & increased sleeping? Is it normal or a worrying sign
