I’ve never heard of this, but apparently others have:

…as I was about to step out the door, I looked down and there was a dead baby kitten on our mat. The mama cat is wild and has never let us anywhere near her. A couple of hours later my hubby went to take out the trash and there was another dead kitten in the same place. He buried them out in the field. I just went outside for a smoke, and there is another one, that makes three.

My question is, since the mama cat is wild, why would she keep bringing her dead babies and putting them on our doorstep? Is that normal for cats?

So one commenter had a thought, which occurred to me as well:

Mother cats can be clearly seen to actually *care* (emotionally) for their kittens, and will fight to the death to protect them, and will risk death to save them – anybody remember “Scarlet” the fire-cat?

Why this mom-cat would bring her dead kittens to your door… hard to tell. Possibly she thinks that you might be able to bring them back.

Wow. Just realized what a heartbreaking thought *that* is.

Yes. Our cat treats us as her bed and her slaves, but she also knows that ultimately, we have a lot of power over her. So one wonders what they think of us, and just how much power they think we have, should we, in our beneficence, choose to wield it.
