If the chest hits the ground, air may escape from the lungs and be forced into the chest cavity. If your cat falls from a potentially dangerous height take it to the vet immediately. Fractured palates can go undetected, but can be repaired if found in time. Let your vet know that the cat has fallen so that he or she will check the cat for HRS complications. Spotting a broken bone is not always easy.
Cats can be very stoic about pain.
A cat with a broken leg will not use the effected leg and there may be swelling around the break site. The cat may hold the leg at an unusual angle or show movement in an area of the leg that should not be mobile. If a break is suspected, do not manipulate. Transport the cat to the veterinarian in the least traumatic manner possible. If you do not have a carrier, hold the cat so the broken limb will hang free.
