Statistical Cats- I was in statistics class and didn't feel like doing the classwork, so I drew the numbers to keep the teacher off my back and decided to include the cats.
Mystical Cats- Still in statistics class, finished the previous pic; brought the song to mind and it was a natural progression to mystical cats.
Scaredy Cats- Still from statistics class. Decided this was a good one to try.
Sillabub- It was an illustration for a fic, but the fic's gone now.
Plato- Same story as the Sillabub one. Lots of people said the sillabub one was my best.
Political Cat(s)- Continuing the theme from statistics class, except I was at home when I drew it.
