Here's an update everyone. The vet said the impact might have caused some nerve damage as well. Hence Kitty isn't able to poop by herself and poop moves only because of additional food coming into the stomach. That kind of explains why he (found it's a boy TODAY) lies in the litter box many times. Vet has prescribed some meds for him to prevent infection, though the fracture must heal on its own. Please pray for him!
