I am trying to find a cat tree for my cats with large platforms (their old one had 18 x 18 inch platforms, but of course they don't make it anymore or I would just buy the same one again). Everything is made for kittens and smallerish cats it seems. My cats are both 10-11 lbs. but they like to stretch out...don't most cats?? Why don't the people who design cat trees know this??
