Toby is 11 weeks old today. He is growing like a weed (weighed 3.5 lbs last week) and doing great in every way healthwise. However, he poops anywhere from 5-8 times a day

. Is that normal for his age or should I look into changing his food? I'm feeding him Natural Balance ultra three times a day and he usually gets around 10 Cheerios a day for potty treats. Thanks!!!
