I was so excited when I saw this product..I thought my cats would live in them...Unfortunately, they are right when they say it fits "almost" any window. I have ceramic window seals and we just could not get it to fit anyway we tried..I was so disappointed when I had to return them......I think they would have loved them.....

Pros: really nice

Cons: can't use on all windows

My cat's love to sit in the window. This item keeps them from sitting on my curtains. It keeps them warm and they love it.

Pros: Cat's love it

Cons: Can't put furniture at the window

I had a window perch similar to this and the cats love it because they can sit next to the window and watch the birds or get warm in the sun. Mine didn't have a heater, though (nice) and couldn't be removed and used elsewhere in the house (also nice). I'd try it if I didn't think my 7 cats would fight over it:)

Pros: versatility

Cons: have to drill holes in wall?

A friend of mine has this for her cat and i so need to go out and get this for mine. My cats are obsessed with sitting near the window and looking out at the birds that are always in the backyard. A comfy bed so they don't have sit on the wooden window sill but still get to look outside. I def recommend it.

Pros: Amazing and comfortable

Cons: Not sure

I bought this as a gift for my daughter's cat who loves to look out the window and also being a cat be comfortable. She absolutely loves it and spends hours a day just watching her world go by. It was pretty funny when we mounted it, we are not that handy, but it was worth the work.

Pros: Cat Loves It

Cons: Not All That East to Mount
