Looking for Climbing Tree

I've seen them in stores.. Petsmart has them 3 feet high. The tag says
that they are made my North American Pet... But, I can't find one tall
enough to entertain a fully grown cat. They actually look like trees. Large
padded base that looks like a grassy hill... Tall trunk covered in long
shag rug. Green pods on the trunk so the cat can climb to the top. AND a
huge green top like you would expect with some exotic tree. but I need one
about 6' tall. I've seen them in Connecticut but the store sold the last
one before I could buy it. One place in Old Town Sacramento CA has on in
their window, but they want 800 bucks for it. The Petsmart version is $100
for the 3' version andthe ones I say in CT weren't much more expensive for
the 6' version.

They look totally cool in the house and are more fun that the artificial
looking ones made of large tubes, boxes and and hemp rope covered poles.

Anyone know where I can find one???? On the west coast?
