The Sunny Seat is a cat seat that sticks to windows with suction cups so you can create a horizontal raised surface for your feline without even having to know how to use a power drill.
In classic infomercial style, they put the “bad” “frustrating” product, in this case, a cat condo in black and white and put a big X for it. Try it. Watch any infomercial and they always use this editing technique.
I have not tried the Sunny Seat but it seems like a crafty person could make their own version at home.
