Tacgnol is the counter to Longcat, as Bizarro is to Superman, Morgan le Fay is to Merlin, and Spock is to Evil Spock. Although the two cats parallel in length, Tacgnol's fur is black and his name is the reverse spelling of Longcat's.
According to the story of Tacgnol, Longcat and Tacgnol are mortal enemies, destined to do battle during an event known as the Catnarok.
Tacgnol is sure to appear wherever outbreaks of Longcat postings occur.
