You're right, this is "Really Great Catfood." Spencer and Alice took to it immediately. In fact, your suggestion to start with one-fourth and gradually increase the portion didn't fool them. They immediately scuffed down the Tuft & Paw, and it was total T&P from then on. They love it!
I love it too, as the content is both healthy and tasty. Although they both drink adequate water, I prefer stew to ensure hydration. You got it right!
The packaging, or rather the box, is a killer for me. I guess it's a lack of hand strength, but I can't tear off at the perforation, so I use my scissors. Then I fumble around trying to get the box open. By now, both cats are circling. After getting it into my hands to pry it open, I place a portion on each bowl. At the next feeding, I want to finish the box, but the food remains rigid. I need to use a spoon, and I never quite get it all out. It's frustrating and wasteful.
But the bottom line is I will continue to order as it addresses my need to give the cats the best because that's what they give me, their best!
(I think a pouch might work better...)
