Twice at day.
Obi doesn't eat much some times, that is normal, ideally will eat 1/2 cup of food on the morning, half on the afternoon. But being realistic, he eats less that it, unless he has been at the office running all day.
2 or 3 times at day, depending on activity and water drink. If he stays at home, he could be just doing it at morning and evening. If going to the office, he can drink more water based on more activity and needs to be taken out just for pee after lunch.
