I heard once that if you do not regularly increase the size of prey that you feed to your BP that their head will not grow properly and remain very small and basically abnormal.

Is this true?? I am concerned because at this point - my bp prefers small prey - she refuses to take larger prey - I don't want her head to stay small and the rest of her to continue to grow out of proportion.

If anyone knows whether this is just non-sense, please let me know.

Thank you.
