This would be the case for a "normal" female, and is the case with my other female who goes through the normal phases of fasting or showing little interest in food to snatching the food from the tongs and leaving the rats tail still in the tongs. This female has never shown those phases, she's always appeared food driven.
She was last fed 26/5/ so I'll offer her another meal tomorrow, and then maintain a weekly feed. Would you guys recommend a 90-110g weaner rat or a couple of multis ?
