I'm sorry she got out. At least she's eaten recently. When my KSB, Serengeti, got out, he was gone for a few weeks. I loked everywhere I thought a KSB would be. Searched the entire condo many times. Then one day, my mom happened to be in the kitchen and turned around to see Geti several feet up on the counter about to get behind the oven. Luckily she grabbed him before he could and he's safe now. Goes to show that they CAN and will climb, even high, slick surfaces.

Try checking behind anything warm, like the oven, fridge, freezer, etc. Also, watch any other pets; they might find her before you do.
