Meet Socks, a feral cat who adopted our family in November of 2012. She won't come in the house or let us pet her, but she spends most of the day hanging around the garden beds and back deck, supervising our outdoor activities.
As the weeks turned into months, I stopped watching closely every time after I'd put the cat's food outside and often enough I didn't bring the food bowl with its left over pellets back inside promptly. This meant the cat's bowl became a regular enough food source to attract the usual scavengers of a slightly larger sort.
Now that I know Socks won't defend her food, I try to pay closer attention and get the bowl back inside whenever she has finished eating. Those cat food pellets are chicken based, and whether or not it might mean anything to that dove to know it is scarfing down a fellow fowl? I find it a little unsettling.
