Wake up call

Earlier this morning I opened the balcony door since the cats love the cool air. Later I woke up to a squawking noise and growling. I assumed it was the cats pouncing each other (they make strange noises when playing) and then I saw a brown object fluttering around squawking. Chipmunk? No a chipmunk couldn't get into my 3rd floor place. I slipped on my glasses and saw feathers. It looked like some sort of wren remaining still until Precious or Frodo pawed at it. It looked adult w/out any baby fluff, but then it is a little late for baby birds. The growling was from Precious. They chased it into the living room and back to the bedroom to the living room and back to the bedroom. It squawked for about 30 min. and I thought it flew back out the balcony door to freedom. I went back to sleep. I wake up to discover a dead bird in my closet with puncture wounds. I grabbed a bath towel and folded it twice to avoid touching it. I picked it up and dropped it off the balcony. Apparently, Precious and Frodo lost interest when it died. When I was filling the food bowls, I saw the same kind of bird go into a hole in the eave outside my window. I have no idea how a bird got into my bedroom. Post later. Bye!
