I hadn't thought about that.  I'm not sure that would buy me much though unless
I lived on 1 level.

A lot of it is the setup of my condo and my day-to-day lifestyle.  1st floor is
kitchen/LR/DR.  2nd floor is laundry closet, my bedroom and the spare bedroom
that she's in.  3rd floor is where my PC is.  I spend an awful lot of time up
and down between these 3 floors.  Unless I got a cage for the couple of hours I
spend in LR at night watching the tube, we could at least be in the same room
for that time.  I would not want her in the bedroom with me because I'd never
sleep.  Even if she never made noises to get out of cage, I'm so highstrung
right now and not sleeping well that the tiniest peep out of her would wake me
up.  (I'm still freaked out from last week when I woke up to her having a
seizure next to me in my bed).

My other cat is this playful tomboy girl and I know she'd always be going up to
the cage trying to make friends and I wonder how the caged cat would feel about
that being that she's blind.    Until I secluded her, every time the healthy
cat got within sniffing distance, the sick cat probably felt threatened and
would swat at her.

It's sad because the sick cat is my first cat, the healthy cat I got 3 years
later.  Sick cat has always been very jealous that she had to share my
attention and the healthy one is so sweet and just wants to be friends.  Once
in a blue moon the sick one would surprise me and they'd be laying on the same
couch.  A few weeks ago I was shocked to see the sick one laying on top of the
healthy one as they slept.

Thanks for helping to set my mind at ease.  She may have as much companionship
with me right now, but I think it's worth the trade-off of feeling more safe
and secure not having to contend with all that stair-climbing, getting around
things and the other cat.
