When Tomoyo was a baby I put Sakura and Tomoyo out for floor time. Since they were still skitish I made a towel tent by draping a towel over 3 stacked decorative boxes and a decorative bowl to hold the towel in place. I made sure all the barriers were secure (my TV, VCR and Playstation 2 are in the bedroom, so they only got use of half the bedroom. They have floor time in the living room these days) and I went to go get some snacks for me and the piggies. I can back and Tomoyo was missing. I looked all over the room and was about to cry when I saw the top of the towel tent quiver. Little bugger had climbed up onto the top box and was hiding under the towel. I had looked on the floor under the towel, not the top box over a foot off the ground.
She used to climb on everything. Even hopped onto the bed by herself one day, but now that she's older she doesn't climb so much anymore.
