Diseases and injuries

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

Whitecough and Greencough
Both are chest infections, caused by bacteria. Whitecough is a mild 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 claimed the lives of several cats.

Medicine cats treat it using catmint. An ancient 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 kittencough is mentioned. Runningnose tells about a herb used to cure it, that has disappeared since.

In Moonrise, Mothwing mentions blackcough as a form of chest infection ; however no cat in the series is known to have contracted blackcough.

One of the largest epidemics known in the book series is in the book Long Shadows, where possibly more than half of the clan, including Firestar himself, fall ill to greencough. It started with Millie and Brairkit before quickly spiralling out of control, giving signs to just how fast the sickness can spread. The epidemic cost one of Firestar's lives, but thankfully no other lives were lost.

Poisoning
Poisoning is the ingestion of a substance that causes harm to the body, such as:
 * Eating or drinking poisonous substances or plants. Usually kits do this, being curious and unaware of the danger
 * Eating poisoned or rotten prey
 * Eating crow-food or drinking tainted water
 * Inhaling too much smoke from a fire
 * Being bitten by a venomous animal

If only a small quantity of poison is ingested, the cat mostly receives a bellyache, but larger amounts can cause the death of the cat. Medicine cats treat it with yarrow or nettle leaves, while mild bellyaches are treated with juniper or watermint.

Rat-Borne Infections
The cats sometimes fall victims to infections carried by rats, although they do not have a specific name for it. An ancient ShadowClan medicine cat, Pebbleheart, realized that rats were a source of disease. As ShadowClan cats sometimes ate food from the Carrionplace in The Forest, they were prone to catch this disease. Burdock root is used to stop infection from rat bites.

Blindness and Deafness
A cat may lose his or her eyesight or hearing due to old age, 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 are usually born deaf.

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.

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.

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 (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 with cobwebs, and applying poultices to prevent infection and help it to heal. Herbs used 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, and then pulling the limb until the bone gets back into its 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.
