Hey, Cinder-pup, reading your account of the various results brought an idea to mind. What about bowls set around with damp towels in them - they'd be way less messy if they got knocked over, and would still be pretty wet, If you wanted to be extra cautious, you could put em in cheap plastic containers with holes punched into their lids, making it very unlikely they'd be spilled, broken, fallen into, or, if stepped on, they wouldn't cause any harm. Ziploc makes those pretty cheap ones you can get in the food-store - and if you don't have lots of spare dish-towels, or old towels hanging around, you could use papertowels or sponges, but I bet they'd dry out faster. The other option is hanging plants so that old Kat couldn't get to 'em to use 'em as litter pans!
