My cats love this as do I, my only complaint is that it is carpeted and having so many carpets in my home my cats do not do well with scratching posts made of the same material, they then feel the carpets serve the same purpose. So for people who don't have a lot of carpeting they will most likely be extremely effective.

Pros: size, weight, durability

Cons: carpeting

These are a great solution to having doorways and furniture scratched especially for smaller cats or kittens. I like that they're mobile, so you can move them from time to time to keep it interesting, the feathers are a big draw and the base is better than some I've seen at lower end department stores.
Disadvantages : Cats like to reach up to scratch and leave their marks/scents - this is short. Sometimes they tip over as well if attacked with enough force from the kitty.
But I like that it can be shared by multiple cats, that it attracts them to scratch and shed old claws.

I still say the larger condo / scratchers are better, but this is a good toy too.

Pros: Great to distract those claws, entertaining and scentable, movable and easy for cats to share

Cons: Small in size, length, sometimes tips over

My cat Kelly absolutely loves her scratching post. We have had her about a year and half, she is on her second one and it is wearing thin. She loves running up to it and scratching to get attention. It's the easiest way to catch her sometimes, when she is scratching.

Pros: Free Standing, never tilts over

Cons: Top wears out quickly if used frequently (bottom using gets no clawing)

This was the first playground equipment I bought my cats. It is great because they love to stretch and scratch on the the stand and post. I also put more catnip on theirs to keep them happy.

Pros: Great exercise

Cons: Rather large

My cat would go crazy for this. She loves feathers and the scratching post along with the feathers is a plus.

Pros: drive them crazy

Cons: no
