Review on 🐾 Tempcore Cat Window Perch for Large Cats - Indoor Cat Hammock with 4 Strong Suction Cups, Holds up to 20 Pounds, Breathable Mesh Design, 360 Degree Sunbathing and Scenic Views by Alexandra Baker

This is actually a very sturdy window seat for a cat. The only problem is I agree with other reviews that it's difficult to suck properly. I washed the window thoroughly and made sure it was dry, I even heated the spots where the suction cups were going to be placed so the temperature of the window and the suction cup were the same. Don't have the cat jump on it right away, leave it there for a couple of hours and see if it sticks. Otherwise, like my cat, they won't want to come back to him when he falls. I don't know, the problem is that the cups aren't very slanted, they're more flat. There are no instructions so go back to the picture to help you.
