Hello everyone, I have been monitoring Opo's actions after sprinkling calcium on the food once a week. I have been doing this for 4 or 5 months just to see if there is a pattern. The problem is 80% of the time after Opo eats the food with calcium in the morning. Opo seems a little more lethargic and appetite is down for the day. More sleeping. I only use a pinch.
