You mentioned teaching him how to be a more efficient killer. I really don’t think that’s the problem here.
He’s perfectly capable of killing a mouse with one quick bite to the neck anytime he wants to.
The problem is he doesn’t think that you are. If you’ve ever watched adult cats with a litter of kittens (either in a documentary or real life) at a certain age, you’ll see them doing the exact same thing. Most times it’s the Mama cat but Toms have been known to help out also.
They stun the mouse and then bring it back to the kittens as an object lesson. Obviously the first few times the kittens just see it as a toy and the mouse starts to run away. But sometimes the mouse is recaptured by the parent cat and dispatched with that efficient neck bite and eventually the kittens put two and two together as hey discover the practical use for their hardwired instinctual play moves.
If you’ve watched kittens playing together you’ll see them doing the neck bite thing (obviously not with killing force)
But, it’s as much a part of their instinctual moves as the stalking hiding and pouncing (and even the little butt wiggle immediately prior to the pounce :)
So, I guess your cat regards you as kind of a “slow learner” in the killing dept. So he keeps bringing you more object lessons :D
There was a really great documentary film a few years go where they also used night vision lenses to capture cats hunting their prey at night.
They also showed several groups of barnyard cats and their litters of kittens at various ages and followed their lives.
It was really fascinating as it showed most of what I’ve described above; I wish I could remember it’s name.
Anyhow, perhaps if you learn that neck bite thing and kill a few of the critters he brings you, he might be able to relax a little and realize that you can fend for yourself so he no longer needs to “provide for you.”
So, get to work practicing that neck bite thingie.
:D
