The first thing you should do if your cat has a laceration that doesn’t appear serious is to clean the wound with lukewarm water. Flush it and then flush it again. You can't flush too much. If you have a syringe, and you should in your cat’s first aid kit, then simply draw up water into the syringe and spout it into the wound. The syringe should never, ever touch your kitty. Your goal is to use the water and the pressure from the water to eradicate the debris from the wound. If you don't (shame on you!) have a syringe, you can use a turkey baster. You can even use the kitchen sprayer on a gentle spray, so it won’t hurt or alarm your cat.
As you clean, you can assess the wound more closely. If the laceration looks to be superficial, you may be done with cleaning portion. Tenderly dry the area around the wound.
If the wound is deep or draining, you need to take kitty to the veterinarian. Some deeper or draining wounds can profit from a bandage. You need to be extremely careful. Veterinarians say that most bandages applied by owners are not done correctly. Don’t ever make the bandage too tight. That is a common mistake well meaning owners make.
Use a 4 x 4 bandage, and then wrap it with gauze. If the wound is open, it’s best to use a bandage material called Tefla. If the wound is draining quite a bit, carefully place the Tefla next to the wound, then apply some absorbent cloth, wrap to hold it in place and keep it on the feline. The classic bandage consists of gauze or Telfa next to the wound, then a cast padding or gauze style wrap followed by an outer wrap consisting of Vetwrap®. A tiny strip of tape can also be used to help secure the outer wrap. You must feel comfortable and confident if you perform this task and it is still very wise to see your veterinarian.
