So I know everyone told me to try california natural but the pet store had a really good sale on evo. So i decided to try evo first before switching to california natural. I am slowly switching him over to the evo from the gentle stomach hills and so far so good. The only problem is that it recommends two cups per day and buster gets fed at 8am and 6pm and by 4pm he is kicking his food bowl around and wining that he is really hungry. Will this go away or should I give him more?
