The snack family enjoying a meal

The Snack Children - or 'Snacklets' are 2 kids, their father is Mr. Snack, and their mother is Ms. Snack.

The bicolor cat, Mr. Inspector, is more prominent in the images, and is likely braver. The tabby stays near the entrance in images, and does not enter the chamber as quickly. The tabby appears to be more timid, while bicolor is more brave, and enters the feeder chamber.
