One of the funniest memories of Pocky came while I was preparing dinner one day. I was looking out the window, and noticed him walking from left to right in my view. He was walking very proudly, and in his mouth was a rather large lizard that was squirming. It was obviously thinking something along the lines "What the hell? How did I end up in this cat's mouth?"
Anyway, he disappeared from eyesight, and about thirty minutes later he showed up at the rear door, asking to be let in. (Probably to get some water.) My wife's working theory is that he enjoys lizards because they're like jerky.
I love it when he kills rats. Heck, I didn't even think there were rats in our backyard. He doesn't eat them, but simply kills them, and leaves them in our yard. I cannot count how many rats I have buried. The non-grass portion of our backyard is becoming a "small creature graveyard." I started to be careful where I dig, because I am likely to dig one up when burying another.
He catches birds from time to time. He finds their ability to fly, as an escape mechanism, to make catching them more challenging.
Our large backyard tree, which is very large, has a couple tree squirrel nests. A couple years ago, Pocky managed to catch a couple baby ones, and completely ate them except for the tail, which I found. These were of the gray variety. The tree also have black squirrels, which I observed to be more aggressive. They chase the gray ones, and also stand up to Pocky. I sometimes hear their exchange in the mornings. He has yet to catch a black squirrel.
Anyway, Pocky is definitely a hunter, protecting us from the wild things in our backyard.
