I’m intrigued buy this handcrafted cat window perch from Etsy seller Jeff Lasecki. The perch attaches to the windowsill with Velcro, no drilling required. It’s made of pine and measures 22.5″ wide and 11″ deep. There’s even an inset piece of carpet on top that is removable and replaceable.
Your windowsill needs to be at least 3″ deep for the perch to fit properly. I haven’t tested the perch myself, but a friend has one and she reports that it is really easy to install and quite sturdy and that her cats love it. Visit Jeff’s Etsy shop Woodpalette for more info.
Thanks to Dara for the find!
