I had a similar thing happen the other week, my Patt throttled a cat over the park. He went missing after the cat for about 10 minutes, when I got him back he had no scratches or marks on him so I thought it had got away from him, it was only when I was walking out of the park that I seen the same cat dead on the side of the path, I dont think anyone seen it happen so just kept it quiet :secret: .
Don't say anything I say, cats kill mice and birds, dog kill cats, cars kill dogs and cat's, it's life.
