Yet another feeding question

So I got my first BP the weekend before last and she's about 5 years old and around 1900 grams. The lady I got her from said she fed her on the 12th and that she's been feeding her 2 medium rats every 2 weeks. Based on what I've seen, 2 medium rats seems like a lot. As I gear up to feed her I thought I should get some more information on what size people think she should eat.

She would be fine with a small or medium every 10 days.

A small a week is fine. If you plan to breed then you might want to up the amount by either 2 smalls or 1 medium.

She's just gonna be a pet, so I'll try a medium every 10 days. Thanks!
