Don’t hate it don’t love it.
Size: 23" x 23", Color: Grey
It’s a two piece and it’s pretty stiff. The dogs like it though.

Cute and Sturdy Cat Scratcher
Size: Large - 27" H
Very nice scratcher that is reasonably priced. Was very easy to put together...literally took me less than 5 minutes. The base is nicely weighted, so no worries about my x-large kitties knocking it over. Well made, study and it's so cute. It's a nice size also. My cats love it. Happy I bought this item and a bargain at the price I paid!

Good value for price
Size: Medium - 25.6" H
Easy to put together, aesthetically pleasing. It is relatively sturdy for a cat scratcher. Kat does not seem super interested in this one and we have several others that he is so I’m not sure what happened there.
