Here I am! I weaned my orphaned kitten Jonah to raw--mice from the get-go. IMO that's the safest way to go w/ kittens b/c mice are the perfect food--all in one package. While adult cats can be fed the "frankenprey" way, with nutritional bases covered "over time," it's harder to do that w/ kittens who are growing very fast and really need to get it all at once. Mice accomplish that.
Jonah was sickly and worm-ridden when I found him in the road at 3-4 weeks. He was on goats milk formula until 12 weeks (decreasing as we went along), but right away I started offering pinky mice as well. In nature, the momcat begins bringing dead prey back to the nest at 4-5 weeks and the kittens start working on that and learning to eat that way while still nursing. It's important to get the kitten off pinkies and onto adult mice ASAP (b/c adults are much more nutritious than immature mice). Jonah was eating full-sized mice by 7 weeks, so honestly, I suspect you could just toss one down now. He will probably play with it -- confine him to a small room like the bathroom. If necessary, cut it to make sure he know what it is (momcat would bring it to him semi-chewed).
PM me and I’ll send you links to the videos of Jonah eating various sizes of mice. This forum doesn’t allow that to be posted here but I can PM them to you. ?
I get mice online here: http://www.americanrodent.com/welcome.html
They arrive still frozen, and if you’re in their “red” shipping zone, shipping is free on orders of $100 or more. Shipping is discounted in the blue zone. I order $200 worth at a time (that lasts 3 cats several months, esp. as I don’t feed them at every meal).
I kept Jonah on mice only until he was about 4 mos – then I started gradually introducing other meats. He now eats quail, venison, beef, pork, and beef and pork liver and kidney. Mice remain his favorite food, though!
I'm working on a website devoted to this topic (weaning to raw), I'll be very interested in your input as you go along!
