Im kinda late to the prey model party because I knew it was feeding raw but that's all I knew. I decided to do a lot of research and it's my understanding that at first there's a little trial and error with getting it balanced but once you do it's actually pretty easy. All you need is a small kitchen scale,meat,bone,organs and some fruit/veg if you want. Follow the 80:10:10 and adjust accordingly for your dog, you can add a multivit in too. Hope I'm not missing anything, but if I can find some good wholesalers in my area I'm prepared to give it a try I think
