No- regular milk (cow milk) can be extremely dangerous to kittens as it can cause diarrhea, which can lead to dehydration and even death. The best milk for a kitten is his mother's milk, but if that is not possible, you can get some KMR (kitten milk replacement) which is basically kitten formula. You can purchase this from your vet or most major pet supply stores. If you are still not sure about what to feed your kitten, please don't hesitate to contact your Vet.
