Worries and Veterinarian care

"Since three days 4 cats are missing from my apartment complex/direct neighborhood... so not normal as those particular kitties know so well where they get their daily food. I am worried sick, of course. However, 10 min. ago I suddenly saw one of the missing 4 directly on my window with a big injury on his back :(((( Will take him to the Veterinarian to be cared for. I am so scared about whats going on..." - Manuela
