Offer every 7-10 days only. Did s/he stop eating as winter came in? If so, it’s likely due to the change in ambient temperature, winters being drier (lower humidity) and a change in air pressure. A similar thing happened to my male banana (fasted for 90 days - lost 100 grams) and I got him to eat again buy changing from rats to mice (one feeding only) and now I am scenting small rats with mice to get him to eat them.
