Large, sturdy and well made
This one took some strength to carry up to my apartment! It is very large and solid, and I think represents good value. There's loads of scratching surface, a comfy bed at the top and hiding places with a dangling toy (which my cat ignores, but that's just her). Mine is by the window and creates a good perch for bird-watching. I only have one cat but this one would be perfect for two or more, particularly the bottom two holes which are connected and would be ideal for play-fights.
