Your Dad's offer sounds great - SimbaStairs! That way he can get up and down with dignity, and not risk twisting anything ... Give Simba a bellyrub for me, okay?

As for Ki and her nails, poor girl. Are her toenails all black, too, like a certain bunny of mine? Thankfully, Miss Hoppy trims her own nails, before she decided to do it herself, it was awful for all three of us. She's only almost four pounds - so we canot even "sit on her" like one can with a dog. So trimming her nails was a two-person job.
