Whenever your cat becomes hurt or injured you must keep two things in mind: inhibit bleeding, and preventing infection. Always wash your hands and wear sterile gloves before touching and treating the wound. This will help keep the wound clean and prevent future infection. If it is a small cut, dab it gently with a clean cloth, gently clean the wound if needed, apply an antibacterial ointment and bandage snugly with gauze. If swelling occurs after bandaging, loosen the bandage. The swelling indicates that the gauze is wrapped too tightly and is obstructing circulation.
In the case of greater injury, try to stop bleeding and apply pressure if necessary. If your pet has suffered a head or spinal cord injury, avoid moving your pet as much as possible. In these cases it is best if you can obtain veterinary attention at your home.
