This is the first I am hearing of this product and must say purchasing one will be one my to do list. Our cats love to look outside, however, we haven't much of a window sill for them to sit on (not to mention drafty windows in the winter). I think our cats will love this product.

Pros: i think my cat will love it

Cons: have to find one somewhere

my cats enjoy this product greatly. It stays warm, but not too warm, for them, and they can still look out my windows comfortable. While its sometimes a nuisance to clean, its worth it to see them so content when they are curled up and sleeping away in it! Neat product.

Pros: cats enjoy it, stays warm

Cons: can sometimes be difficult to clean cat hair from.

I like the idea that this bed can be warmed. The high sides will keep out window drafts too.

Pros: a warmer

Cons: none

I bought the thermo kitty sill because my cat loves to lie on the desk while I work and gets in the way. I put the thermo sill on the window that is next to the desk. Without the warmth from the sill, I don't think my cat would stop sitting on the keyboard.

Pros: Cat loves it, extremely easy to install

Cons: none

I need to get another one of these. I only have one and my two cats fight over who gets to lay in it. The only complaint that I have is that I hate the way it looks in the window. But you have to make sacrifices for the ones you love : )

Pros: my cats fight over it

Cons: I hate the way it looks
