If you have a cat you know how much they love boxes and bags.
Leave any random box or bag lying around and they will be in that thing in seconds flat.
This is Simba, our male orange tabby that we got about 18 months ago. He loves his box.
Eventually we will throw that box in the trash and replace it with a new box, and he will love that box too.
He loves all the boxes.
And bags. Any paper or plastic bag that he can fit into becomes his new preferred hideout so he can keep a close watch on all of us.
Of course sometimes a cat can get himself into trouble trying to get into tight spaces.
