How good is Wanpy cat food?

Wanpy offers many cat food varieties; the best-selling is a freeze-dried dual-flavor complete cat food with a high meat content, and the added plantago and cranberry powder help protect urinary tract health. In addition, it adds chicken fat, salmon meal, and fish oil to provide rich unsaturated fatty acids that improve coat quality. However, it uses corn gluten meal to artificially boost crude protein, and also adds a little wheat, so it is not a low-allergen formula.
