This is a great question...as I am syringe feeding now and I want to ensure that I don't over do it. I have fed him about every couple hours, he has taken about a 1 ml of the hills a/d, and about 5-10 ml of water...He seems to want more water, but I don't want to over do it. I also don't want to keep him from him eating his kibble. I am hoping now that he is getting something into him that he will be interested in eating his dry food.
