They are humanoid with feline characteristics such as fur and cat-like facial features. Werecats are nimble and have keen senses. Notably, Werecats do not have tails like real-world cats do.
- Werecats may have night vision as one of their racial abilities.
- Crunchyroll and Yen Press both call Werecats "Felinoids", whereas "Werecats" (ウェアキャット) comes from the Japanese Log Horizon wiki (it is not used in the official publication). Crunchyroll also called them Werecats in the first season, but then switched to Felinoid during the second.
