6. Those little cylume lightstick braclets are awesome for marking you flashlights, radios, water jugs, cat, furniture and other stuff you need to see in the dark. Amazingly, ones I activated on Friday night were still glowing faintly Tuesday night! They are really cheap right now for Halloween so by several containers of them. Also, they come in assorted colors so you can assign a color to a particular type of thing (yellow for flashlights, blue for water, evil green for cats, etc...)
10. Scoop out the kitty litter during daylight hours. It's really hard to do by the light of a flashlight.

A solution suggests itself, if you can figure out a way to get kitty to eat a bracelet, or if the luminescence persists after liberation frm the plastic tube and passage through the feline digestive system.
