Oh, God she is!
She has a habit of dragging her kills into the house through the dog door, which she’s learned to use - and bringing us the eviscerated mouse, rat, lizard or gopher - right into the bedroom for us to find in the morning.
Still, I got a bumper crop of pomegranates for the first time in years - the tree rats used to get them, they crawl along the wires. Not any longer.
When she isn’t killing something, she likes to lay in our laps and purr.
What with the coming food shortages, squirrels might be about to become an important source of protein. Good thing there are so many of them!
When they bring the kill to a special spot, they need a reward from their employer. :^) Back before warfarin, rats used to be ubiquitous here in The Boonies (this is according to the old folks, who, alas, are no longer around to tell these stories). A local butcher shop had a professional catcher who lived in the store (try that now...). The cat would be waiting inside the back door, with the rat kills all lined up, waiting for liver from the boss. :^)
My cat Divot (now deceased) would - when I lived in a ratty old trailer - sit and kill mice all night long sometimes where they were getting in through the wiring for the washing machine. It was kinda nerve-wracking to listen to but it kept them out of the food.
