Toiletia, like most creatures, are not immune from unwanted invaders. The principal parasite of toiletia moscovius is pianazhopus, a pale sometimes green four-limbed chigger which enters the animal through an available orifice and comes to reside in the lining and gastric glands of the abomasum (the true stomach).
Pianazhopus pollute the lining or mucosa, cause irritation and interfere with the digestive function of the stomach causing it to swell excessively with sediment buildup. Symptoms included unnatural rapid weight gain, damaged hide, malodorousness, poor appetite, and sluggish behavior.
Since parasites are found in almost all forage situations, toiletia are likely ingesting pianazhopus at any common grazing or nesting location. A strategic prophylactic regiment is recommended every spring when pianazhopus numbers increase after a winter of dormancy.
