Felis Somnius (Fee-liss Som-nee-iss; Felis-Cat, Somnius-Dream,)

Tabby cat-like Wesen. Extremely rare, less than ten have been documented, most famously by Charles L. Dodgson in 1855. They have friendly, domestic cat-like features when woged, much like a cleaner and more reserved Klaustrike, but with noticable darker patterns and stripes. Their main danger is due to potent pheromones they release that have severe halluciongenic properties that can last for hours.

They show the most radical change in personality when they woge. Several of the documented specimins had jobs as butlers and maids due to their passive and polite nature in human form, but when woged they become wild and unpredictable. Though not violent, they show signs of insanity and become difficult to control. Suspected to have originated in the British Isles, only two have been documented in other countries.
