Pack of 3 coyotes attack and kill near Capitol Hill
Around 3:30am this morning Jack, our beautiful and sweet neighbor's cat, was attacked and killed by a pack of 3 coyotes. I woke up to a loud bang and jumped out of bed to find out what was going on. I did not see anything, but 5-10 minutes later I hear a horrible scream and ran outside. I was shocked to see 3 coyotes running down the block from my house. I chased and yelled at them and they dropped a cat, Jack, just barely alive.
