Flea bite allergy is one of the most common skin sensitivities seen in cats. It tends to be seasonal, becoming more severe during the warmer months of summer and autumn when flea populations are at their peak. For cats that are hypersensitive to flea saliva, even a single flea bite can trigger intense itching that lasts for hours or even days.

Notoedric mange is highly contagious among felines, and often spreads rapidly between animals in close contact. If left untreated, it can cause severe discomfort and long-term skin damage.
