Apart from dragons, cats are the only creatures known to absorb magical energy, but no one knows what they do with it. They are also instantly able to recognize witchers and exhibit an obvious disdain for them, like hissing at them. Cats can also see through invisibility.
- Glutton, Nivellen's cat
- Nibbles, Tamara's cat
- Merlin, Assire's cat
- Codringher and Fenn's cat
- Sorel Degerlund's cat
- There are also werecats, large creatures that are half-human and half feline with powers to bind other similar beasts, such as panthers, to themselves.
- In The Witcher 3: Wild Hunt, using the potestaquisitor (quest item) to find magical energy will lead Geralt to a nearby cat, leading to him uttering the lines "ah, there you are" or "damn cat, ffwshhht!".
- Like in certain real world cultures, seeing a black cat crossing one's path is considered a bad omen in the Witcher lore as well.
