Yeah, it's rare to have a rabbit with an overall good condition at this age. Aki is 8, she's also in pretty good health even if she lost her eyesight a few months ago. The optical nerve just stopped working (she's half albino, with eyes which look purple-ish, and the REW gene apparently causes this pretty frequently - from what I read, a lot of REW have a bad eyesight to begin with). She adapted really well, but it made her even more skittish which doesn't really help with the fact that her guts are less efficient than before. To be honest, she was always pretty high-strung - she was born in a burrow in a garden with no human socialisation before I got her and it shows: she has incredible instincts and she's distrustful as hell of everything and everyone... But well, not seeing doesn't help.
Still, she's eating well and running around and lounging on her carpet so I think I might still have some time with her. I hope she gets to see her 10th birthday too, especially since she lives with a 3 years old rabbit and that they are really well bonded. I'm actually wondering if I'll take another rabbit in when she passes. Rabbits are incredibly stressful to care for. I'm not scrutinizing my dog half as much. I sometimes wonder how simple my life would be with two dogs or a dog and a cat instead of the 2 rabbits and the dog (finding a petsitter who will care for both, a vet competent for the rabbits, riding the train... everything is just sooo complicated).
