I remember the day I brought her home to foster; a kind person who found her had shut her in a cardboard box and she was ANGRY! She was shrieking and hissing and acting pretty feral. I put her in the bathroom with a bowl of food and a comfy bed and taped a "CAUTION, ANGRY KITTEN" sign to the bathroom door. When my hubby got home, he opened the door cautiously to peek in and she was all relaxed on the bed, not angry at all anymore. Apparently she just didn't like being put in the box. (Not that I blame her)
