Saw your post about Dixie. Glad she is doing well. My hubby is in emission from lymphoma (I wrote you earlier on your thread) and is doing what he can diet wise. There is a supplement called EGCG which is an extract of green tea. It has a good reputation. We looked at all the brands for potency and found Piping Rocks to be the best, we both take the 600 mg. might be worth a try as a supplement you could sprinkle it on some wet food.
My first visit there last week was to give the raw food diet a go and see how Dixie responded to it. She seems to be thriving on it currently and has much more bounce and energy - not to mention appetite. So I will move full speed ahead and will periodically give an update.
