Very good content, What would be handy is if you make an additional chart that has the foods alligned in the specific color groups rather then alphabetically so you could print a list of the best foods to give on regular basis would make it easier to remember or take with you to the shop.

Also when the chart is finished it would be a very good idea to make it in other languages as well, For example I'm not natively english speaking and even though my english is good I do have trouble with the names of vegies,herbs and fruits. It would therefor be very handy to have it in my native language. Also that way I could print it out and hand it out to petshops together with a careguide and such.

Looks:

It might be better to change the background colors as they are rather harsh which makes it diffecult to read the chart, Softer and lighter colors would make it much more user friendly. Also the traffic light idea of the previous posts is a very good idea. If you don't have time to do that I would be more then happy to do that for you.
