This is Wren's favourite box. She sleeps in it. She plays in it. She rips bits off of it. And unfortunately, it's splitting at the sides and won't last much longer.
I hope I can get her another the same size sometime. I'm considering buying one specifically!

Wren in the same box, looking bright. Her eye flashes in the light. It's only one day later but the sides are splitting and it's even more chewed.

Wren the one-eyed tabby cat, curled up in a cardboard box that is slightly too small for her. It's bowed at the sides and the flaps have bite chunks out of them. She rests her cheek on the side.
