Pros: Cheap, easy to find, grain free, cats like it
Cons: By-products, unnamed meats, lots of fish
I use Friskies to bring down the overall cost of my wet food rotation. The pate formulas are, surprisingly, grain free, which is great. I'm not crazy about by-products and unnamed meat sources (poultry by-products, meat by-products, "fish", etc.), but my cats like the food and do well on it. There aren't any unnecessary fillers like vegetables.
I've tried even cheaper brands with similar quality ingredients lists, but my cats throw up. They've never vomited Friskies and they've never turned it down. It's not my favorite food, but we could definitely be doing a lot worse.
