Hi... I just adopted a six-month-old kitten, and I have an eight-year-old cat. They have been eating each other's food (I have traditionally free-fed), especially the older cat eating the kitten's food. I don't want him eating kitten food because it is high in calories and he is already overweight. So, do I need to stop free-feeding and put them on a regimented schedule? If so, what are the best times to feed them? Morning and evening? Morning and late night? Any advice would be appreciated. Thanks!
