You can also purchase 1 t8 from animal plastics...use the divider and keep 2 in 1 T8
having multiple snakes is like having multiple anythings...you just need to get them all on a set schedule, stick to that schedule and give yourself enough time to take care of your pets needs and any issues that may arise.
I have 3 snakes...and its no harder than taking care of 1....just takes a little bit more $ for feedings and a bit more time once a month for complete cleanings...(i spot clean as needed)
in some ways having more than 1 can be easier- mainly b/c you know what you will and wont need equipment wise and b/c you already know how to care for one...
