1/3 cup twice a day is to much I think.... When I fed kibble I only fed Godzilla 1/4 cup twice a day and he might be a pound or so over where he should be... So that being said if the weight problem is that serious I don't think your gonna have any luck switching to a better kibble because blue buffalo is pretty decent.
If I were you I would try switching to canned entirely. Much healthier for your kitty and I'm sure it would take weight off much easier than kibble (if you can even accomplish losing weight with kibble :/ ) so there's lots of good brands out there but I caution you that when your looking for canned you try to avoid the ingredient carrageenan. It's in almost all canned pet foods and studies have found that it contributes to the risk for cancer.... Pet food companies are art slowly weeding it out though.... Here are some quality GRAIN FREE brands that do not contain the ingredient:
Soulistic "In Gravy" varieties
Natures Variety Instinct
Taste of the Wild Rocky Mountain
Ziwipeak and GO Naturals have informed us they will soon be removing carrageenan from the ingredient list... When I don't know. But you can be on the look out if your interested in those.
Out of that list Weruva and Soulistic are really low in calories and they are cheap for the quality they are. I don't know if you have a petco in your area but Soulistic is a Weruva brand made exclusively for them and I buy 8 packs of 5.5 oz cans for only 11 dollars. Actual Weruva and taste of the wild for me is hard to find in my area so if you wanted them you could order them online from a site I like called Chewy.com. No sales tax and its always a flat rate shipping of 4.95 IF you don't spend over 49 dollars then its FREE....
their prices are usually a dollar or two cheaper than the stores also. Saves trips for me and my stuff gets to me in only about 3 or 4 days. They've shipped same day for me or the next morning so they are quick.
Natures Variety is a good food and they have a lot of protein sources to choose from than the norm. They are just a bit pricier so I only use a few in my rotation.
If someone knows of any other grain free cans without carrageenan please add to my list! And someone correct me if I'm wrong but I believe you wanna feed 1.5 or 2 percent of your cats body weight a day if your trying to take weight off of them.... Remember to split that amount into at least two meals. Godzilla only gets a half a can once a day and 3 table spoons of Honest Kitchen Prowl.
If your wondering about what honest kitchen is. It's a dehydrated raw cat food that comes in a powder. You add water to it and walah the next best thing after completely raw! It comes in 4 lb boxes and a 4 pound box is equal to 12 pounds of food. At only 41 dollars! My cats love it and its extremely healthy and not to expensive! You can get that at chewy.com too. It would be a good choice for you also. Here is Honest Kitchens Website where you can read more about it. I believe you can also get sample boxes from their website too.
Hope this helps!
