Potential prey size for adult retics.

Disregard other post... Wouldn't let me correct title...

So what could I be looking at for a potential prey size for a 14 ft. Female retic?
Minimal to max fed once every 7-10 days?

Asking because I'm looking at getting a female that may reach that size..

Large guinnea pigs or rabbits. You won't be able to get by with rats :/ I would also expect something larger than 14 feet for a female retic.....
