Why not try F/T?
The signature lines are code for the quantity of whatever morph/reptile and their gender. For example:
1.0 Banana BP
Would be one male Banana Ball Python.
1.1 Dogs
Would be one male and one female dog.
The first digit is the quantity of males, the second digit is the quantity of females and in some circumstances 1.1.1 would be one male, one female and one un-sexed/unknown gender.
