Well, if there is absolutely no average...I'll ask a different question.

I have a 0.1 normal. She's 460 grams (finally weighed her yesterday) and 5 years old. I've recently gotten her eating weekly. If she continues to eat weekly, would you expect her to grow much, or do rescues not grow well?

I'm just wondering if BPs can have their growth stunted by bad feeding/husbandry, and if the growing years are only usually when their young...
