For Navi, the left cat, we call her Chunka Munk, Plasticat, and Ms. Infected Lips.
For Scorpi, the cat on the right, we call him Mr. Small, Spider Cat, and Crybaby.
Any mix of words with pussy, like, when she is mad she is spicy, a spicy pussy, so she's a spussy. I also love to call her fat nugget because she is the exact colour of a nugget.
