Hi alls, Asterix is 10 months, has lived with me for about a month now and is doing great. He came to me with serious food allergies and I had to promise his breeder that I would feed him raw either till such time as it was sure that he had outgrown his allergies or else, failing that, forever. He is an accomplished food thief so sometimes steals junk food, in which case he will break out in red spots all over his body and very nasty looking ulcers in his ears. I live in a vegetarian co-op and we're basically junk-food free, so he's only had one minor allergy outbreak since coming to live with me. The breeders makes her own food, but recommended Darwins (over Rad Cat, which is local to me and which she used to feed the cats, but because it doesn't contain bonemeal, prefers Darwin's). I've been feeding him both Darwin's and Rad Cat, because he briefly had an outbreak of diarhea which I think came from the bone meal in Darwin's, so now I alternate back and forth and he's had no problems. My question is this: I have a beef liver in my deep freeze that I got as part of a beefshare. Frankly, I'm not going to be eating this. How much can I give to my cat? Both Rad and Darwin include liver in their formulas, so I don't want to over do it with liver, since I know too much Vitamin A can be toxic. But how much is too much? I ended up giving him two 2" by 2" pieces today and yesterday. I fear that was too much. Could I give him like an 1"X1" piece a week? Sorry, I don't know weights. Thanks for any advice!
