Cat is said to have been the first potion created specifically for witchers. The concoction allows witchers to pursue monsters into their lairs, including dark caves, ruins and crypts, because it augments vision to pick up additional wavelengths of light. To prevent blinding, the imbiber's pupils automatically narrow when in bright light. This is possibly the potion most commonly used by witchers.
