I hope to do some breeding next year. I own a home. My one concern and it may be a little goofy would be breeding or owning too many animals in a apartment or duel occupied residence of multiple units.
My concern would be along the following lines.
Ball Python's are an investment of time, emotion, love and money. I would not trust living in a multiple dwelling unit where the actions of others could cause an event like a fire or what have you. I know that may be being overconcerned.....and events like that can happen anywhere...but raising large groups of animals where you have to deal with other people and the behavior would make me nervous.
None of this may make sense but having the apartment burn down because someone 3 doors down left their curling iron on or thru their joint in a wastebasket and burned the place down would drive me nuts lol.
