Thanks! Yuki, the Lynx point is half the age of Kylie and yet she is the same size. Though her head is small and neck is short, she looks like a Cheetah more than a cat, it's weird. I used to just cut holes in them and leave them in the kitchen too, but Yuki loves to dive into them and they both move the boxes around. I use the 24 soda can boxes too.
This condo is stuck together with hot glue and tape. It's too hot now-a-days because of summer, so they are very lazy cats until a cold day shows up. They lay around in the 'dead cat' position, lol. Kylie knows how to pry open the door to the basement. ^.^
But Yuki is a crazed hunter, always wanting to catch something.
