A cat with a gastrotomy tube must receive 300 kcal daily. A 15 oz can of food has 1500 kcal. The food must be diluted with water 50:50 so that it is thin enough to fit through the tube. A maximum amount of 45 ml can be given at each feeding. How many feedings does the cat need daily

well, you have to feed 1/5 of a can, dilute with water, or 2/5 of a can in volume. Now what is the volume of this?

I don't know the volume of a 15oz can.
