Your pet will get sick and they do no recover until you do something about it. Your pet will continue to lose hit points, be unable to fight in the battledome, and become more miserable until it's cured.

They can be diagnosed at the NeoHospital, and the cures can be bought at Neopian Pharmacy or other such stores. A disease can also be cured at the Healing Springs in Faerieland once every 1/2 hour, but may require several visits because the healing process is random.

Diseases can also occur as Random Events, or may be triggered by an item such as Rotten Omelette or Poisonous Jelly. You could also get it from the Wheel of Excitement which features a different disease your Neopet can be afflicted with every few months. Also, some weapons of the battledome have been known to cause sickness.

As of July 25, 2006, there is a current total of 35 diseases, but new ones are always being added to the game.

Item that cause diseases:

There are some items either food or battledome weapons which will bring disease to your pet. Some people enjoy making opponents pets sick with weapons in the battledome. Although infecting a pet with food is usually a newbie mistake, sometimes owner will purposely infect their pet by giving a pet a different disease so that it's cheaper to cure.

There are some species whereby they can get sick by eating certain foods which will not affect other species.

For example:
* Kyriis can get Itchy Scratchies from Apples.

* Quiggles get Neezles from eating Ice Cream, and other "cream" foods, because they are cold blooded and their blood changes temperature according to their surroundings.
