Post your most outrageous theories about the series. I'll go first:

*ahem*

Janus' cat is Crono's cat. The facts:

* At the end of Chrono Trigger, Chrono's cat jumps into the portal.
* Cats appear randomly throughout the game's timelike (such as the cat falling into the pit when chasing Ozzie)
* Janus' cat appears to be purple, but in the original Japanese translation of CT, it is said that the royal family dye their hair purple to show off their high status in society. That includes Janus. That includes... his cat.
