A couple of days ago, King's out by himself in the back yard. Molly's acting like a loon, and wouldn't go out. I was fixing dinner and I see King flying towards the back left corner of the yard. I look and due to the trees really needing to be trimmed, I can't see anything. I go to the door, and can hear a cat hissing and yelling, and King is ducking and King is ducking and weaving, trying to "get" the cat. I kind of doubt he wanted to hurt it, he wasn't upset or angry at all. Cats have always been a "toy" for him. When I get out far enough, I can see that it's a really big black cat and he has it cornered and it looks like it's scared to death. I call King, but he's hypnotized by the cat and wants to play with it. Finally I try to catch King, that's pointless, but he finally screws up and comes up and sits for about a quarter of a sec or so, and I grab his collar and he instantly flails and about twists my fingers off, and gets loose. The cat is really trying to slice King's face open, but he's missing all the swats, and the cat's getting tired. All of a sudden, I hear Molly flinging herself against the back screen door. All she needs to do is hit the latch and she's out. She WILL kill the cat, she has no use for them, and if anything with four legs is in HER yard, they will go down. I have to make a move, if Molly gets out, the neighbor's cat will be a rag doll in a few seconds. She already killed one a few months ago, and only had one tiny scratch doing it. When I start walking up to the cat, I realize it's a neighbor's cat, so I gotta try to save him! I grab King so he tries to bail out and keep away from me, and I figure that will give me a chance to grab the cat and toss him over the fence. Just as I do, and get scratched a couple of good ones, and Molly had crashed through the door and missed the action only by about 5 seconds or so. She was so devstated..She was on alert all day..
