Well after about 3 days, they all caught on that if they didn't eat within 30 minutes that I would take the food away. Now they all seem ravinous each time and are eating their food much better. Another thing that I like is that there's much less waste in their litterboxes. I was having to clean them out 2 times a day but now I only need to do it 1 time a day. They also seem much more alert and active. I should have fed them this way a long time ago. BTW that's a cute pick of Mitzi.
