Hello! First of all, calm down.
Okay, the things you want to look for in a cat food are meat and lots of it! No by-products at all. Stay away from corn, wheat and unknown meats (ie "meat meal", "poultry".) Meat should be the FIRST ingredient. Preferably the second one as well. Try and stay away from grain heavy foods. In my honest opinion, I do NOT think Eukanuba is a high quality food. It consider it hmm, a step up from Cat Chow or Whiskas. But no where near high quality. Is PETsMART the only store you can purchase cat food at? If so, I recommend Blue Spa Select. It's a decent food, not the best, but certainly better than Eukanuba. The canned formulas are exceptional as well. These are the ingredients to Eukanuba Kitten (which I assume you are feeding):
Chicken, Chicken Liver, Chicken By-Product Meal
, Brewers Rice, Fish Meal
(source of fish oil), Corn Grits
, Chicken By-Products
, Chicken Fat (preserved with mixed Tocopherols, a source of vitamin E, and Citric Acid), Dried Egg Product, Dried Beet Pulp (sugar removed), Natural Chicken Flavor, Brewers Dried Yeast, Calcium Carbonate, Potassium Chloride, Vitamins (Vitamin E Supplement, Niacin, Ascorbic Acid, Vitamin A Acetate, Calcium Pantothenate, Biotin, Thiamine Mononitrate (source of vitamin B1), Pyridoxine Hydrochloride (source of vitamin B6), Vitamin B12 Supplement, Riboflavin Supplement (source of vitamin B2), Inositol, Vitamin D3 Supplement, Folic Acid), DL-Methionine, Choline Chloride, Minerals (Zinc Oxide, Manganese Sulfate, Copper Sulfate, Potassium Iodide, Cobalt Carbonate), Rosemary Extract
All the undesirable ingredients are bolded.
Chicken by-products can be anything, really. As long as it's connected to a chicken. Feet, beaks, feathers, whatever.
Fish meal-what fish? Salmon? Menhaden? Herring? Who knows.
Corn Grits- Corn is a filler, as far as I'm concerned. It's a major allergy trigger and cats can't digest it very well.
Now, compare those ingredients to Blue Spa Select Kitten:
Deboned Chicken, Chicken Meal, Whole Ground Brown Rice, Whole Ground Barley, Oatmeal, Chicken Fat (preserved with Natural Mixed Tocopherols), Rice Protein Concentrate, Rye, Whole Cranberries, Whole Sweet Potatoes, Whole Carrots, Herring Oil, Menhaden Fish Meal, Alfalfa, Ground Flax Seed, Sunflower Oil (preserved with Natural Mixed Tocopherols), Sea Salt, Barley Grass, Whole Eggs, Natural Flavors, Calcium Phosphate, Taurine, Dried Kelp, Lecithin, Parsley, Spirulina*, Yucca Schidigera Extract, Lactobacillus Acidophilus, Bacillus Subtilis, Bifidobacterium Thermophilum, Bifidobacterium Longum, Enterococcus Faecium, Choline Chloride, Turmeric, Zinc Amino Acid Complex (source of Chelated Zinc), Iron Amino Acid Complex (source of Chelated Iron), Vitamin E Supplement, Argenine, Lysine, Manganese Amino Acid Complex (source of Chelated Manganese), Copper Amino Acid Complex (source of Chelated Copper), Beta Carotene, Potassium Amino Acid Complex (source of Chelated Potassium), Niacin, Vitamin B12 Supplement, Vitamin A Supplement, Calcium Ascorbate (sources of Vitamin C), Calcium Pentothenate, Rosemary Extract, Thiamine Hydrochloride, Riboflavin, Cobalt Proteinate (source of Chelated Cobalt), Vitamin D3 Supplement, Folic Acid, Biotin, Pyridoxine Hydrochloride, Potassium Iodide, Menadione Dimethylpyrimidinol Bisulfite (source of Vitamin K Activity), Sodium Selenite
I admit Blue is grain heavy, but it's the best you'll find at PETsMART. Notice though how is contains no by-products, unknown meat sources or corn.
Do you have a Petco near you? They sell some good quality foods such as Natural Balance and Solid Gold. Good luck!
