I feel like that's got to be such a satisfying tree to climb as a cat. Claws in the bark, nose in the holes with an exploratory pawtip, and an easy descent if you're not quite the climber you thought you were on the way up.

What a beautiful cat and tree

That's not a tree, that's the Whomping Willow

One of mine would have a field day with that tree. He'd probably go right up some of the branches.

Buffy the weird ass ghoul tree slayer.

The tree reminds me of "Harold" from Fallout 3

Interesting.

Good tree, better cat.

If you get another cat, would you keep them inside? Our two fellas are strictly indoor cats, and I feel a little bad... but then read horrible things like this and it's nice to know the biggest threat they face is being stepped on because they're being dickheads.
The birds and bugs are grateful too. Unless they find their way into to "the killing zone" ie inside.
