I too agree with Ladymom, but wanted to add one thing - I don't know why you think they might not gain as much or lose weight on raw. That certainly isn't true of my two. They are both doing extremely well on raw and Kalina and Matty Lu are anything but skinny. The thing I like about raw is that they NEVER have an off day - they eat all their meals with gusto, which is not true of them before I put them on raw. Good luck.
