If you plan on college, as someone previously mentioned, then getting any more pets is a bad idea. If not (or will continue to live at home), put a plan together that includes:
- plan for security of the snake, people and other pets (cage, locks, etc.)
- plan for economics of it (cost of food, heating, etc.).
- get a male retic (smaller than female) or "dwarf" retic
If you show your parents a well thought plan, you may convince them of the merits of having a retic. As others have stated, it is not a casual decision, but doable if you have reasonable intelligence and dedication. Good luck.
P.S. Don't do as I did 20 years ago when I was in college - I secretly kept a retic under the dorm sink - I wrapped the hot water pipes, installed a light, etc. I had to always make sure the "maids" did not find it. Nowadays, which are certainly worse for individual freedoms, etc, you would probably get thrown out of school. Too bad "my days" were better. Progress,
people?
