Diseases and injuries

Cats living in the wild often fall as victims to a number of diseases and injuries. It is the job of the Clan's medicine cat to treat these conditions.

Chest Infections
Whitecough and greencough are the most common chest infections known to the Clan cats. Whitecough is the milder form, but if untreated, it can develop in the much more severe greencough. Cats usually catch it during leaf-fall and leaf-bare, and sometimes it develops into large-scale epidemics. It can be fatal for elders and kits, and it has claimed the lives of several cats.

Medicine cats treat it using catmint. The first ThunderClan medicine cat, Cloudspots, found out that this was the best remedy. If fevers accompany the cough, tansy or borage is used as well.

In Into the Wild, a disease named kitten-cough is mentioned. Runningnose tells about a herb used to cure it, though it has disappeared since Twolegs came to the forest.

In Moonrise, Mothwing mentions blackcough as a form of chest infection; however, no cat in the series is known to have contracted blackcough. Blackcough symptoms are such as expelling blood, high fever, and coughing.

Poisoning
Poisoning is the ingestion of a substance that causes harm to the body, such as:
 * Eating or drinking poisonous substances or plants such as deathberries. Kits are the ones who usually fall victim to this, being curious and unaware of the danger.
 * Eating poisoned or rotten prey or drinking tainted water.
 * Inhaling too much smoke from a fire.
 * Being bitten by a venomous animal such as a snake.

If only a small quantity of poison is ingested, the cat usually just receives a bellyache, but larger amounts can cause death. Medicine cats treat these bellyaches with yarrow or nettle leaves, while mild bellyaches can be treated with juniper or watermint. If a cat has been severely poisoned (as in eating deathberries, as Sorrelkit does in The Darkest Hour) he/she may become unconsious for a length of time.

Rat-Borne Infections
The cats sometimes fall victims to infections carried by rats. One of these infections is called Carrionplace Disease. An ancient ShadowClan medicine cat, Pebbleheart, realized that rats were a source of disease. As ShadowClan cats sometimes ate the rats from the Carrionplace in The Forest, they were prone to catch these diseases. This happens in Rising Storm when two ShadowClan cats, Littlecloud and Whitethroat, come to ThunderClan for help because their Clan is in chaos from the deadly and contagious disease. Yellowfang sends them away because she doesn't want ThunderClan to become infected, but Cinderpelt wants to help them and comes up with a cure. Nightstar dies from Carrionplace disease during this time, which is why the Clan was in chaos (they thought it had ripped all nine lives from him when in fact he only had one life because Brokenstar was still alive). Burdock root is used to stop infection from rat bites.

Loss of Sensory Perception
A cat may lose his or her eyesight or hearing due to old age as One-eye of ThunderClan did before her death or from accidents and infections, or birth defects. These conditions usually end their career as a warrior, as they cannot hunt or fight efficiently, and must retire as elders. Kits born with defects usually die young, unless they have special skills compensating it, like in Jayfeather's case. Kits that are white with blue eyes have a higher chance of being born deaf, like Snowkit.

Joint Aches
A condition usually associated with elders, the joints gradually degenerating with age, causing pain and difficulty to move. Damp environments can cause the appearance of this condition, so apprentices must make sure that the moss they gather for bedding is completely dry. It is usually treated using daisy or ragwort poultices.

Toothache
A toothache is caused by a cracked tooth, cavities, or an infection in the mouth. Alder bark is used to soothe the pain.

Fever
Fever is an abnormally high temperature of the body. It is not a disease in itself, but it usually signs the presence of an infection, such as greencough or an infected wound. If needed, it can be treated with feverfew, borage or lavender.

Chill
Chills are mostly associated with cold weather or being submerged in cold water. Although this condition is mild and is not a disease, it has claimed the lives of Mosskit and Hollykit. Kits and elders are more at risk of dying when they get a chill. Licking a cat's fur the wrong way gets the blood flowing again. A poultice of lavender, catmint and feverfew is also a good remedy.

Cracked Pads
The paw pads may crack while walking long distances on hard surfaces, or due to cold weather. Elders are especially prone to this condition. It is treated with a poultice of coltsfoot or yarrow. Dock leaf poultices are also used to cool cracked pads.

Other Diseases
Several other diseases were mentioned in the books, however, the cats do not have names for it. Examples include the conditions of Pebblefur and Shellheart (a painful lump in the stomach, most likely a tumor), or Tawnyspots.

Wounds
Wounds are injuries when the skin and the muscles beneath are torn, cut, or punctured. They may put a cat's life in danger due to blood loss, infections, or the damage of the organs. Wounds are the most common injuries, due to the cats always fighting enemy Clans, badgers, or foxes.

Minor wounds heal on their own in no time, but severe wounds must be treated by a medicine cat. This treatment includes cleaning it thoroughly with the tongue, stopping the bleeding by pressing cobwebs on it, and applying poultices to prevent infection and help it to heal. Herbs used in the poultices include goldenrod, marigold, burdock root or (in the case of rat bites) wild garlic. If the wound becomes infected, chervil or horsetail is used as well. The pain can be eased with poppy seeds or willow bark.

Sprains
Sprains are injuries to ligaments of a joint, caused by being stretched beyond their normal capacity and possibly torn. It causes severe pain and decreased ability to move the joint. The cat must rest for several days.

Joint Dislocation
Joint dislocation is the displacement of a bone from its normal joint. Medicine cats treat this condition by first feeding the patient poppy seeds to make them sleepy so they don't feel it as much, and then forcing the limb back into the joint.

Broken Bones
A broken bone is usually the result of an accident, such as falling down from a high place, or being hit by a monster. Cats most often break their legs, and while medicine cats try to bind the bone with cobwebs, the injury usually results in the cat remaining crippled for the rest of his or her life. The only cat known to fully recover after breaking a leg was Cinderheart. A more severe injury is when a cat breaks his or her backbone. This results in the cat being unable to feel or move parts of his or her body. If the break is bad enough the cat will be killed on or shortly after impact.Briarlight broke her back bone, and as a result, her back legs no longer function.

Chest Infections
Chest infections mentioned in the Warriors books come in three stages; whitecough, greencough and blackcough. Little is known about blackcough; the black may be blood.

It starts with Millie and Briarkit before quickly spiraling out of control, giving signs as to just how fast the sickness can spread. The sick cats are isolated at the Abandoned Twoleg Nest to avoid getting the healthy cats catch the disease. No single-lifed cat dies, although Firestar loses a life.

 * Greencough original name was blackcough. The name was changed before publishing Into the Wild, as it was thought that the new name reflected the disease better. Revealed on Vicky's Facebook page.
