I'm looking at Amarkat:
Or this one from Foster Smith-- because of the cedar pretty much
Or.... for some milder whimsy:
I can afford all three (though not together :-)). I think all 3 are tall enough. But I haven't heard anything here about Foster smith (I buy a from them quite a bit), though never a cat tree or savvy kitty. (They get good marks for toys but I have not seen reviews for cat furniture.)
I have one Maine Coon Siamese mix 16 lbs. and I am planning on getting a kitten in the spring sometime. I just got a little pay raise and I promised Padfoot he could have a new cat tree. I have some cheapo thing from Petsmart or Petco that is of a very poor quality, so no more of that.
I am open to other suggestions, but I don't like the clunky looking stuff.
