Why do cats bite?
There are several possible causes of biting in cats, it depends entirely on the situation at the time. Biting is primarily the result of fear and or aggression. Some cats, especially young ones may also bite as a form of play.
It can not be emphasised enough that this behaviour should not be encouraged, and in fact, it should be actively discouraged. It may be cute when it's a little kitten nipping you, but when it's a full-grown cat, with a much stronger jaw, it's no longer a laughing matter.
Injured or scared: No matter how friendly your cat is, if he is injured or afraid, he is at risk of biting you. He may not even be aware he is doing it. This is why an injured or scared cat should ALWAYS be approached with a great deal of caution.
Breaking up a cat fight: A very common cause of pet owners being bitten is getting between two cats having a fight. This is an absolute no-no. If you need to break up a fight, throw a towel over them, get a broom and gently try to prise them apart, do not use your hands, arms or legs to split them up. That is a recipe for disaster and a trip to emergency is a likely outcome.
It should also be mentioned that once you have broken apart a cat fight, your cat(s) are likely to be agitated for quite some time afterwards. It is a good idea to maintain some distance between you and your cat(s) until they have had sufficient time to calm down.
During a seizure: A commonly held belief is that a cat having a seizure is at risk of swallowing its tongue and well-meaning pet owners have been accidentally bitten by sticking a finger in the mouth to stop this happening. A cat will not bite its tongue during a seizure and for your own sake, keep fingers away from a cat having a seizure.
How to stop a cat biting:
Start as you plan to continue. Never encourage biting in kittens or cats when playing. Avoid roughhousing them. If your cat does bite you when playing, say a firm "no" and stop what you are doing. Repeat this until the cat learns that biting means the end of play time.
If you are handling an injured or scared cat, proceed with caution. Even the most placid and laid back cat can bite if scared or in pain. Have somebody on hand to help you, and wear thick gloves and a long sleeved top to help protect your hands and arms.
Read the body language. A frightened, scared or aggressive cat will often display signs such as ears pinned back, eyes wide open and flickering as if looking for an escape route, large pupils, skin rippling, tail twitching.
Remember, hands are for petting, not biting.
How to treat a cat bite:
According to the Cornell Book of Cats, around 1 in 170 people in the United States receive a bite from a pet every year. Children being the most frequent victims. Between 40-80% of cat, bites will become infected. When a cat bites, their razor sharp teeth pierce under the skin and bring along infectious bacteria which then becomes trapped and multiplies, causing infection. Pasteurella is the most common bacterial infection resulting from cat bites. It is found in the mouth of between 75-80% of cats.
Signs of an infected cat bite include pain, swelling, oozing or pus, heat, redness in the affected area.
If you are bitten by a cat, wash the area immediately with antibacterial soap and apply an antiseptic such as betadine. Apply pressure to control any bleeding and then go straight to your doctor. While you are there, you should discuss with him if a tetanus booster is required.
Do you know the rabies status of the cat who has bitten you? Rabies is transmissible from cats to humans and is a major concern. If you have been bitten by an unknown cat, even if it is a minor bite, seek medical attention immediately.
