So, Smokey and Sunny have been on an exclusively grain-free diet for a few months now (Blue Buffalo Wilderness dry and Sheba wet) and I must say, I'm very impressed. Sunny's "issues" of being sick (for whatever unknown reason) are gone and she is now very frisky (she was not before). Both Smokey and Sunny have very nice looking coats and they don't shed excessively. Sunny still needs to lose some weight but that is just because she and Smokey need differing amounts of food (Smokey is incredibly active and needs quite a lot more calories/food than Sunny). I attribute this seemingly better health to eating a diet that is meat-based instead of corn, wheat, soy, or rice based like some foods on the market. While some cats seem to be fine on the cheaper foods (Friskies, "Purina Be Happy", Deli-Cat, etc) I do believe that the reason certain medical problems (feline diabetes, feline obesity, hyperthyroidism due to too much salt in the food like many cheaper foods add, kidney problems, some types of cancer, etc) in cats have become more common is because of the food. Obviously not all cases of these diseases are because of the food but quite a few could very easily be traced back to improper nutrition (cats are meant to eat meat, they evolved to do it and we should, therefore, feed them appropriately).
I feed two different brands of food (the Blue Buffalo and the Sheba canned) simply because, if there is a recall of either one, I will have less trouble getting the cats to eat something that they are already used to (a big deal for Sunny who is quite picky and will go hungry instead of eat the new food).
If anyone has tips to get Sunny to lose weight (I know exercise is the key but am not sure how to get her to do it!), If anyone has an idea, leave a comment below!
