the halloweenmath package the best math package for LaTeX including functions for cats I think, still cannot even easily square-root a cat with it (without also have to include a witch), why don't someone make a m LaTeX cat-math package?
suggested minimum functions: black cat, white cat, Norwegian forest cat, Schr{\"o}dinger cat, fat cat, kitten cats, top cat, cat-woman, egyptian cat, dead cat bounce, cat with 1 to 9 lives...
So yes I can get the cat out, but not the witch, lacking functionality, not able to do proper QM, only old QM
