I suspect that box will be far too big for the apartment!! LOL But I have just sorted some stuff out and have emptied a couple of small boxes for her to play in. She's gone very quiet - hiding somewhere, so will now have to go look for her (with the box) to make sure she's ok! (Just realised she' been quiet for a while )
Found her - the bonus of her legs nearly always moving is that when she hides somewhere, I can usually hear her knocking on whatever she's hiding on!! LOL
