That is a lot of food...how has her weight been? If you've been feeding that much for a while and she's not getting fat, then maybe that's what she needs. The 5.5-6 oz per day is just a starting point...needs vary amongst cats, some more....some less.Wow.. SO it seems I have been over feeding! I had been doing either 2 5.5 oz cans or 3 of the 3 oz cans. Since we have 3 oz cans right now I will go with 2 a day. Thanks so much! She is 2 years old btw.
