The list of ingredients is quite long and sciency, so please take this advice with a grain of salt.
I broke down the ingredients into categories:
Freeze Dried Mealworms, Freeze Dried Crickets, Chicken Meal, Fish Meal, Potato Protein, Fructose
Not a typical food for cats, but I guess it won't cause any damage.
Corn, Potato Starch, Corn Gluten Meal, Soybean Meal,
I wouldn't recommend this much starch in cat food, but in a snack it's ok.
Poultry Fat, Soybean Oil, Fish Oil, Coconut Oil,
All are safe for cats and sound tasty for a cat.
This one is tricky. Fully ripe tomatoes are safe for cats, but green tomatoes contain proteins that are poisonous for cats. You never know if all tomatoes processed for this product where ripe.
Calcium Carbonate, L-Lysine, Dl-Methionine, Salt, Spirulina Algae, Canthaxanthin, Lactobacillus Acidophilus Fermentation Product Dehydrated, Streptococcus Faecium Fermentation Product Dehydrated, Dried Bacillus Subtilis Fermentation Extract, Saccharomyces Cerevisiae Fermentation Product Dehydrated, Dicalcium Phosphate, Choline Chloride, Natural And Artificial Flavors, Vitamin E Supplement, Calcium L-Ascorbyl-2-Monophosphate (Stabilized Vitamin C), Ferrous Sulfate, D-Biotin, Yucca Schidigera Extract, Zinc Oxide, Manganous Oxide, Niacinamide, Vitamin B12 Supplement, Mixed Tocopherols, Rosemary Extract, Copper Sulfate, Calcium Iodate, Vitamin A Acetate, Beta Carotene, Calcium Pantothenate, Sodium Selenite, Folic Acid, Riboflavin, Pyridoxine Hydrochloride, Thiamine Mononitrate, natural and artificial colors, menadione dimethylpyrimidinol bisulfite (source of vitamin K3), vitamin D3 supplement, cobalt sulfate
Many of those are minerals and vitamins, but I have no idea what half of that list actually means.
Riboflavin and tocopherols are common ingredients in cat and dog food. Rosemary extract for example is known to cause seizures in cats and dogs, but as always, the dose makes the poison. Copper sulfate is poisonous for cats as well, but is nonetheless found in cat foods in low concentrations.
I won't recommend feeding this to your cat on a regular basis or in bigger amounts. Maybe half a teaspoon once in a while as a treat won't do any damage, but not more than that. Please keep in mind that I didn't check every single ingredient for its suitability for cats and I don't take any responsibility for the health and safety of your cat.
