Growing cats need bigger trees

The kitties have graduated from climbing the much smaller trees on the grounds to exploring the much larger 40+ft tree in front of our unit.  And those brave little farts are coming within a foot of the very top of it.  We've seen them up there swaying in the breeze.  How they come down is pretty smart, too.  The branches form a bit of a spiral staircase and they just walk on down.  There's maybe a six foot jump at the bottom when the branches end but that's no sweat for these cats.
