I would re do the living room... MAKE IT HUGE... with some walls to section it off into different types of rooms.. one would be mostly glass with some plantation blinds.. this would be Tinky and Jupiter's room since they love to lay in the sun... I would have some really cool cat trees and a cat safe plant garden so they could dig in the dirt and chew on some grass and plants...

Then one room would be for Eric's entertainment system... his tv and stereo stuff is just too much for our small living room.. and I would make it sound proof so when he watches movies it won't bother me while I am in....

the other room... a library.. with a big fireplace and a comfy cozy couch and some plants in there too...
