Rami: do you have coyotes, or other criters, in your neighborhood? In our area we have coyotes around every night. Sometimes it's hard to sleep they're so loud. Outdoor cats are just so problematic in terms of their encounters. They don't run away like a dog will-at least mine will. We also have some fairly ferocious owls around too but they usually go after rabbits. Good luck with your injured cat. To save its life you may end up with a three legged cat. If so he-or she-won't know the diff.
