My tree tried to be a ballerina & failed OR Cats are @$$holes....take your pick

So the other day before we left Demon Spawn showed a sudden interest in the Tree.  You know how you know a cat is interested in something?  Their eyes dilate so much they are basically black (one reason for the nickname Demon Spawn) and they do this weird crouching tiger wiggle butt thing.

So she was doing that on the back of the couch while looking at my Tree.  "No!!! Bad kitty!!!  Do NOT even think about it! I will hurt you". She said "Meow" and walked away.  I took that as an understood "Don't touch the f**king tree".

Remember how the Tree is anchored to the wall?  Yea well apparently when dealing with @$$hole felines you need TWO anchors.  We got home to a toppled over tree, a handful of broken ornaments and cats no where to be found.  It had done a 45 degree spin (I think that's right), moved about 2 feet (our anchor must not have been taut), and landed against the couch (I think this saved most of my ornaments).

Tree down, tree down!!!

Once we got the tree back upright we noticed something odd.  I mean besides all of the ornaments being off the damn tree....how'd it do that?!??!  When adjusting the tree there was a perfect hole in the side that was facing the couch.  A perfect cat sized hole.  A hole that was just below chest level on me....perfect height for an old cat to jump.  Then we noticed another hole about a foot higher.  This one was smaller but still cat sized, hmmmmm.

Conclusion one of the cats jumped from the couch and landed in the tree.  The other cat saw their sister in there and decided to join her.  The momentum of the 2nd cat hitting the Tree plus the combined weight of two cats on one side of the tree caused it to spin, moving the tree two feet before it went off balance and fell over causing The Great Tree Fall of 2015.  There are now TWO anchors holding the tree up.  If I get home later and it fell again, I'm gonna murder some cats.

How I envision the Cat-astrophe going down (based on the evidence):
Old lady: Hmmm I haven't climbed the Christmas Tree in years...
Demon Spawn: Heeeeeey I wanna play
Old Lady: No...bad idea.  Go away
Demon Spawn: *butt wiggle* I'ma goin'
Old Lady: *hisssss* this will not end well
Demon Spawn: *Leaps off the couch* Ha! 
Old Lady: Hey, I can do that too!!! *leaps into tree* Well that wasn't so bad....
Demon Spawn: See, its fi.....f**k f**k f**k Ahhhhhhh
Tree: *pirouetting* 
Old Lady: Dammit I can't believe I let you talk me into this *jumps gracefully onto the couch*
Demon Spawn: *spazzes out* *tries to climb higher* *fails* *falls chaotically onto the couch*
Tree: I'ma fall now
Both: F**k we are so dead
Dogs: WTF is going on in there?!?!?!?!
Both: Nothing....
Dogs: Can't blame it on us this time
