One of the main reasons I'm still feeding my cats kibble is because there is small but noticable improvement in their teeth health when they eat their special 'oral care' kibble.
That is, until they went on a diet two months ago. They now think their two small rations a day is akin to torture by slow starvation; they scarf it down like inmates in a North Korean prison. I just noticed yesterday that this involves not actually chewing the damn stuff. Hence, defeating the only positive reason to feed kibble aside from convenience.
So, time to try yet again to home make the cats' food. It was probably only a matter of time, anyway, but this was the last straw. I'm going to try harder this time. And of course everyone says switching off kibble will help with the losing weight anyway (and reduce the risk of diabetes, and increase fluid consumption, etc, etc).
