Deer are prey animals. Canines and Felines are predator animals. That deer saw a predator that would otherwise kill her baby, since domestic and
wild are not distinguished by wild animals. So, the deer did what nature told her to do. Eliminate the greatest threat first. Then, she went after
the next predator that was a lesser threat.
Notice, the cat initially protected itself by cowering at the first challenge. It was only when the cats natural Feline instincts took, namely
swatting her claws at her aggressor, did she become a significant enough threat for the deer to react.
And, I agree with those of you that fault the humans for this. Letting your domestic dog run free around wild animals makes for a pathetic human.
That dog has no idea how to address such an adversary, whereas in the wild, a coyote or wolf would make a much more evenly matched opponent.
