Stairs: Going up I'm okay balance-wise, though I do almost always go one foot up, pull up the other, repeat. I lean forward like a football player running with the ball (don't they?). Besides MS balance issues, I have arthritis, so something usually hurts.

Going down is trickier. I feel as though I'm pitching forward, even when I'm not.

I'd really hate to be catless. Mine aren't given to rubbing around my ankles and truly getting in the way, but it's true that you don't know what you're going to get. I'm probably no more apt to trip over a cat than I am to trip over my own toes, but I still always ASSUME one will suddenly dart in front of me. I don't walk around in the semi-dark, either.
