By definition only if you put a male and female snake together on purpose (with the goal being to get baby snakes) are you truly breeding.
However the laws in different states/counties/areas differ and sometimes just the fact you have more than 1 of the same species of animal means you are a breeder regardless of what you plan to do with them (i.e. in one Indiana county if you have more than 3 dogs you are considered a breeder...even if all 3 are fixed and that means you need a license)....strange laws.
