The tricky question is whether a domestic cat can be traumatised by observing traumatic events unfolding before him or her. In this video (which you can see by clicking on the link above the picture) a ginger tabby and white cat watches the family dogs fighting over a ginger plush cat toy as if they are tearing it to bits and killing it. Does the cat see this as dogs playing or as dogs killing a cat? We don’t know. It is likely that the cat is not traumatised and that he just sees dogs playing. However, it would be nice to get into the head of cats more accurately rather than using guesswork.
