Where is the Girl? (IV)

This was the girls' old pet taxi which we improvised into a cat bed (throw in a cushion plus a towel). Grimlock washed it and had put it aside for drying.

Guess who this might be?

"Sssshhhh, don't let the other two know I'm hiding here. Pretend that you didn't see me."

"Surely, I could do with some time-out."
