Do you know of any cat therapy?

About two weeks ago I was doing laundry. As I do every week I just threw the laundry bin into the washer. Now my cat was pregnant and I haven't seen her in a few days, I had assumed she was having her kittens somewhere in the garden or shed, as she usually do. Unfortunately I did not realise that she had the kittens in the laundry bin. To my dismay I realised this when I went to take my laundry out of the washer, eight dead kittens were infused with my clothes, it was horrible. I buried all my clothes from the wash along with the kittens. Since them my cat has really started to pit revenge against me, she just scratches everything and even tries to attack me sometimes. My friend told my that I should rub some of her poo into her then this would show her that she should respect me. I've tried this and a few other prescribed remedies, but nothing worked, she only seems to hate me more. I would like to know if anyone out there knows some form of cat/human therapy which can reconcile our lost relationship or you think buying her other kittens would work?
