Dead animal day.

None of the pets, thank goodness, but it's what they brought me.   One of the dogs showed up with the south-bound end of a north-bound rabbit.   Then there was a scuffle over it with the dog and a couple of the cats.  It was grab and run time.  About an hour of so later one of the cats strolls toward the garage with a bird in its mouth.  Why or why do they feel the urge to bring you what they just killed?   One time I opened the garage door and there was a big pile of pin feathers swirling about, never found the rest of the bird.  I know they kill and eat smaller animals but I would rather not be included in their feasts.  Yuck!
