I keep food out all day long for Casey. She is only 3lbs. so I like to make sure she has something to eat whenever she feels like it. I measure out her food and give her 1/4 cup. This usually takes her two days to eat this much. She likes to eat later in the evenings...from supper time til she goes to bed. Sometimes I worry that she isn't getting enough but I have learned just to watch her...she will eat when she gets hungry.
