These are one of the best things to have in your home for your kitties. My cats love getting up high and its a better alternative than them climbing up and ripping furniture.

Pros: perfect for indoor cats

Cons: n/a

I don't have this particular shelf but it's a great idea and I think I'm going to make some for the shelter. Cats enjoy heights and this shelf is multi-purpose.

Pros: Great Idea

Cons: None

My cats just all pile on this so they can all see outside from this exact spot..all together! lol
Its really great for them....I love it for them!

Pros: Lets cats see the world outside our home

Cons: None that I'm aware of...

We have a cat shelf and they are great. Our cats are able to sun them selfs. In our case it also allows them access on and off our porch.

Pros: Great for the cats

Cons: Can look out of place

We have an outside cathouse and have shelves all over inside and outside. The cats love it and chase each other up and down the shelves.

Pros: easy, cheap, fun

Cons: none
