My friend A of A Girl and her Dot just sent me a link to a cat hammock in a box:
Cat Hammock in a Box
This is quite a handy cat accessory, because now you don’t need to worry about throwing out the item that you purchased for your cat that came in the box, because the box itself is the item! Unfortunately for me, I have one of those kitty nail-file/scratching post things lying around, unused. My mom bought it for my sharp kitties, and they have never used it. But they do like the box:
Squeaky enjoying her box.
She is always sleeping in here.
Relaxin' in a box
I should sell cardboard cat boxes and get rich.

Well if you and your kittys have no use for the scratching post I’m sure Evil Kitty could use it

The perfect gift a “Kitty In A Box.” When I first got Dottie, she LOVED toilet paper and paper towel rolls. That does look like a fun box with the crinkly paper.
