This covers both a system of twelve planets around a yellow sun and three of those planets in an offsite orbit as one world. Planet One, the innermost planet, is the seat of government and the primary manufacturing planet. Planet Two, following a half rotation behind, is primarily farming and residential for most breeds of cats. Planet Three, a half rotation behind Planet Two, is exclusively for the Big Cat such as lions, tigers, bobcats, lynx, etc.
Catdromida’s day is one rotation in a cat, but by human earth standard, it is 26 hours. This holds for all three planets.
