Cat--yeah, those leaves looked a little too 'perfect' to me. It WOULD be insanely cool to build a house around an indoor tree. If I could keep a ficus alive, I just might give it a go! 

Very Very Cool!  Don'tcha just love ETSY?  These are whompen pricey..and I think that ironic since their site tells us the reason they came about was because the "pet store" ones were too expensive...LOL 

Oh and I looked it up: They are made with real tree branches but they are not live trees: and thus they do not need to be watered or otherwise tended.   On the other hand.... Whoa insanely cool would it be to actually do that!

Take a live potted tree (that the cat climbs anyway....darn it) and bulid a happy little home around it.  I bet out Maven could do it!!

i take it back, those are real trees. These items are not for the faint of heart, then.

I'd honestly prefer a fake tree... I have enough maintenance in my life already without having to water my cat's toys, too. :)

Those look totally awesome, and though the trees may have been custom grown into those shapes, it doesn't look like there's a big enough space to contain the roots you'd need for a tree that size - even larger bonsai need larger pots. I could be wrong though, photos do lie.

Regardless, I'd be proud to own one of these things for my cat. She'd go nuts for it.

those tree houses are great - a bit pricy though!!
