With just one cat, I have,
One large litter box (under the bed type storage box, long for a long boy!)
Cat tree by a window,
2 beds, (one in the living room, & one in the bedroom
(his blankie in one, one of mine in the other,
)
A large carrier, w/ a bed inside, also in the living room,
A pad covered cushion I made w/ some left over carpet padding in the bedroom window sill,
A crate pad in the living room window sill,
bags for the litter box waste, a "poopy pale" for the poop bags (an old Epsom salt container),
Water & Food bowls,
Feliway diffuser,
Brushes, furminater, (sp?)
A large basket full of toys!
....I think that's everything.

Now why does that seem so familiar...
