one time I felt sooo bad, Cookie was just a little thing, about 3 months old, and I opened the frig door, it sticks at times so I really pulled it, and wham! hit her in the head!

and I went to move the cat tunnel over, with my foot and there was Callie in it! (just one of the "kicked" stories ) but it was not very hard, just enough to scare her AND me! now I LOOK first.
