I'm pretty picky about dog and cat foods because in my brood we have a mix of allergies, sensitive stomachs, prior urinary blockages from food with higher amounts of magnezium, panic attacks... etc, etc.
Swtiched all dogs, cats and kittens to Innova Evo mixed with some raw and now no allergies, no sensitive stomachs (actually we even switched to this food cold turkey and had none of the switchover symptoms), no panic attacks. My vet actually likes it better than the prescription food for Az's urinary problems due to its low magnezium level (keep in mind this is the Evo, I don't know the mag level in the regular innova food). Everyone's fur is the softest its ever been. Peewee feels like velvet now and even Karma who has a rough Labrador coat is silky smooth and glows (someone said once it looks like we use shoe polish on her
) Gemini is a senior cat and was losing weight, now she's a perfectly healthy weight. Karma and Boo had gained weight on other foods, now they're at perfect weight too... and I never have to measure their food on this. I free feed everyone and these are the results.... and I firmly believe this is due entirely to the food being grain free.
Actually, pardon my babbling for a second, but I even got into an argument with my MIL about this. She's a former vet tech who railed on me because I feed my dogs beef bones. Told me it was dangerous. I told her no, COOKED bones are dangerous. Raw bones are just fine. When she then went on a roll about certain "good" dog foods I then pointed out that these "good" foods are generally loaded with corn and are the same foods that have made both my and her animals sick in the past. "And besides... think about animals in the wild. They're carnivores. They eat meat and bones. When is the last time you saw a wolf or a lion sitting in a field grinding corn?"
Sorry for the long post, but animal nutrition is a hobby of mine and I've spent a lot of hours reading about this. I firmly believe we should keep an animal as close as we can to a natural diet for their own health - and I think this about humans as well. If you choose to feed a kibble/canned, given the current options out there I do believe Innova Evo is the closest you can come to your own cat's/dog's natural diet, and the health changes once we switched to Innova in my cats, my mom's cats and my dogs are proof of this.
I'll get off my soapbox now
I can't help myself... I'm pretty passionate about this subject
