A Tigon is a human bred big-cat, produced from a Tiger and a Lion mating.

A Tigan is an alien species, who resemble felines, made up by me. Tigan had the misfortune to be named when I was a stupid(er) 12 year old. They have been called Tigan for 7 years.

I've had way to many people try to correct me. XP I understand why though...Kinda.
