Fuzzitus is a disease.
Description[]
While no symptoms are known (besides the drop in stats and mood that all sick pets get), it is described as an "allergy to fluff", that all pets occasionally contract, and which is "especially bad" for a JubJub.
Its main cure is a powder called Fluff-B-Gone, but it can also be cured by Warm Amber Ointment, Cooling Ointment, and the Healing Springs like all diseases. As the name suggests, Weak Fuzzitus Cream can cure Fuzzitus, but is unreliable and may not work.
