A ferrel kitten adopted us last year.  I am allergic to cats but my husband loves cats. He is an outside cat so we put put his cat tree on our covered porch and he loves it.  Easy to put together and very sturdy.  He loves the scratching post and the platforms he sits on to look in the window to call for my husband.  We will put it away for the winter, but it was certainly worth buying for the pleasure he gets out of the cat tree.
