Just what is it about boxes?

Doesn't matter how uncomfortable it is but why do cats feel compelled to climb into any box that happens to be about? Our Tuxedo cat's one here is reasonably cat-proportioned but our Fruitcake cat never turns down the opportunity to sit in a box of tissues with her paws all neatly inserted in the mouth. She then sits there serenely looking as though it's a completely normal sort of thing to be doing.

Back to Mrs S this morning: clipping more heathers, trying to eke out what is left in the water butts and rescuing a very pot bound but very beautiful rhododendron.

Then trying to help Z sort out her bank account: some unknown person succeeded in processing several PayPal transactions through it  (at 2am this morning!) leaving her woefully short of cash. Fortunately PayPal are being unexpectedly helpful in trying to recover the funds but it'll still be 5 days before her account sees the money again. As if she hasn't already got enough on her plate.
