An absolutely amazing experience from beginning to end. We didn't realize we had 24" studs and bought this fort which is 16". Customer service was so helpful and prompt in reworking the design (and the scratching ramp we also bought) to fit our 24" studs, and we only needed to exchange the canvases. They make the process so easy to put the tree up and it's even easier to change it around to fit your needs.
Only slight downside to note is our cats did not like the ramp-it was too wobbly for them. Maybe they would have liked it better if it was shorter like the 16" design is supposed to be. But that was easily solved by putting a little cat tree in its place and adding a shelf for them to get up the fort instead. We'll definitely be back to add on to this creation!
