re: Climbing/Nesting Modules

Been lurking along here Ross, when you go, you go all in 🙂

Now in a cat free house, but when we had two of the buggers, they were "blessed" with multiple cat trees. Nothing as elaborate as what you are building, but a few holes and tubes to ponder. Turns out they never bothered with the passages, they just scaled the side, King Kong style, just to reach the coveted top penthouse. I suppose kittens will go ape over all the ambush positions if there are a few of them to form teams!

looking formidable!
