i agree - if you kill the yote or whatever it is - you will get deer, and the pain never ends. Better to find the balance early then to be forced to find it later.
Personally, when I am back in Oregon, I leave the cyotes alone since they keep the rest of the garden deer free - now if you were a rancher - I could see why you would hunt them, but other then that, you could be causing yourself more pain down the line.
also, leaving food outside is guanranted to attract something. . .
