I have a senior who's experiencing dental problems (he recently fractured one and had to have two others pulled), but doesn't like anything but dry food. He's very finicky and already too thin. I finally got him to eat some wet, but he won't eat enough of it to sustain his weight. He likes to free-feed/snack throughout the day, and I'm gone a lot). His current kibble is, I've noticed, very thick -- almost round -- and rock-hard. I'm considering several different alternatives, including Purina Cat (or even Kitten, for the added calories) Chow and Fancy Feast, both of which look flatter, thinner, and crispy rather than dense. Obviously only a cat could answer, but could anyone comment whether or not these take less tooth force to bite?
