I am so sorry. PLEASE PLEASE dont let Duke around any more kitties.

My dog did the same thing, was raised with my kitty Kilo, and one day just turned and well... Did exactly what Duke did. BUT Kilo did not die fast

I never could trust Angel again, and I gave her to my mother. I could not even look at her the same again. Instinct on not.

I hope that Loki went fast, and that you can heal from such a tragedy
