Thank you, ZulusMom.
For general info, I did a search for "calories" and found other similar recommendations -- first time search has worked. I think I had always previously tried from the 'Home Page', and it never worked; but I did this from this forum, and it did! This will be helpful in future.
btw, this is so ridiculous compared to what he is eating right now (or, I should say, what he is eating right now is so ridiculous compared to the recommendation)! I was right to start wondering. He was always a free feeder, on dry food, prior to the diabetes diagnosis -- but also of course, at least 25% overweight.
Still, he has not gained weight in the last week. I wonder if other health problems complicate the picture. I will keep watch. Am glad to have the general recommendations to refer to.
