Shelby & Seymour get fed 3x a day..... and the are 4 years old. (We are on a schedule and have been following it for a LONG time)
They each get 1/8 cup at 5:30 AM, 1/4 cup at 4:00 pm, and 1/8 cup about 8:00 pm.
It is funny, but they seem to know what time it is........ they are "asking" for their food when it gets close to feeding time.
