Review on 🐱 K&H Pet Products Deluxe Kitty Sill with Removable Bolster Tan/Kitty Print Unheated - 14 X 24 Inches: The Ultimate Window Perch for Your Feline Companion by Melanie Lewis

I wasn't sure what to expect but the only piece of metal in the whole product is the zip part so lots of plastic. I wasn't sure if the velcro would be strong enough to hold it on the windowsill without drilling holes. At this point my cat weighs 6 pounds. Kitty and the velcro keeps it on the windowsill well, it has plenty of strength, expect it to hold its weight for a long time. Once she's reached her expected adult height of 12-15 pounds we'll see if he holds up. She's hanging on screws just in case as she likes to hang out in my office window all day while I'm working. Expect to enjoy it even more when it's warm enough outside to open the window. The cover can therefore be removed for cleaning and can be configured with a cushion on the window or room side of the base. Very happy with this purchase, as is Anya.
