I call her Juggernaut, she just plows through everything. She climbs everything, falls off everything, smashes her head on everything, and laughs at it all. I'm glad I padded the whole floor of our tiled downstairs or we'd have been to the ER about 50 times...god bless gym foam tiles. She doesn't seem as bothered as we are, but it's hairy, no doubt...we've had to retire or turn every chair in the house on it's side, block off access to my recliner, etc because she climbs them, but doesn't seem to mind falling from 3' up when she climbs the back.
