Yep, just what we need, another thing to worry about:Angry cats raining from the skies. Last month, an elderly man named Gao Fenghua was walking his large dog in Harbin, in northeast China . . . when a cat fell from an apartment building and landed on his HEAD. The cat wasn't hurt, but the impact knocked Gao unconscious.And Gao's dog was NOT cool with that. So the dog confronted the cat . . . and the cat started swiping at it.Gao wound up spending 23 days in the hospital with a neck injury and he still needs physical therapy.He's looking for a settlement from the cat's owner.
