There is some friskies that is low carb. While I don't love the option Basic stopped eating the FF a month or 2 in. Keep that in mind. Also, not sure if you use Chewy to order things, but it is a very impressive company as far as how they handle returns and their customer service as a whole is the most impressive I've seen in many years. If you have a petsmart near you, they allow you to return items too. I've had to do it throughout this entire ordeal because my cats are picky too. I'm hopeful you find a low carb food he will like.
I haven't heard anything, but I also haven't been looking. I only learned of Dr. Elsey’s after I ordered, my cats had problems, intro'ed very slowly, and then went searching for info on it. I was shocked at the reviews and message boards covered in complaints of GI issues and vet bills because of it. It doesn't bother all cats though. Dr. Elsey’s has no intention on returning to the previous formula either.
Any lower numbers are welcome, when they are running that high. I'm glad he got under 400, even if it was barely.
I hope you are able to relax this evening. You're doing great, Deb, whether you realize it or not.
