Sorry if this question sounds so ridiculous that it shouldn't even be asked, pardon my ignorance, because I'm new to cats, but what would (relatively speaking) be the better of the two (or less worse) between Purina's Cat Chow and Friskies dry kibble? I know they're both supermarket brands and the most cat foods available, and have lots of ingredients that cats shouldn't eat, but how bad is supermarket kibble like Purina's? I mean, I haven't heard of cats dropping dead from Cat Chow/Friskies, unlike some other cheap brands. I know the first ingredient should never be corn. Cat Chow has 'poultry-by product meal' as the first ingredient, so I'm inclined to prefer Cat Chow, rather than Friskies, even though both have wheat gluten, and artificial preservatives, etc. Then there's Purina ONE, which is one step higher, that has "real meat" as the first ingredient. Is dry cat food really all that bad for cats? I leave it out for my cat, but her main meal is grain-free wet cat food. I think I'm leaning to favouring dry food is partially I've heard wet food is bad for cats teeth, and kibble is supposedly better. When my cat eats kibble, she crunches on them. Is at least leaving dry food for cats OK, but how much does it matter for the brand? What are good grain-free dry foods available in Canada that are fairly cheap?
