I have just switched my cats to scheduled feedings, and the two girls are fine with it, but my boy gets pretty antsy. He was homeless for awhile when he lived in Toronto, though, so I think he's still not totally sure he isn't going to starve. I do a small meal in the morning, a snack as soon as I get home from work, and a meal before I go to bed at night. Three things I've found helpful so fare are: immediately wash the food bowls and put them away to dry. That way no one is staring at an empty bowl and dragging it around the floor all day. Second, almost 100% of the time that I've fed them dry at a scheduled mealtime, since they've actually gotten HUNGRY by this point (which they still aren't used to) they over-eat, the kibble expands in their tummy and somebody barfs. Feeding canned food essentially eliminates this problem, as it's already wet and doesn't expand. Lastly and most importantly, SAVE THEIR BIGGEST MEAL FOR RIGHT BEFORE YOU GO TO BED AT NIGHT. Otherwise you may be woken up by yowling kitties way before your day is scheduled to start.
Hope this helps!
