You do not need a grinder to do raw. You can purchase what is called a premix, put chicken meat and skin into a food processor along with the premix, and viola, raw cat food! The premix of course adds expense, but it makes it easy and removes the grinder requirement. You can also feed frankenprey style and not have to use a grinder.
After this whole experience I have done a lot of reading and learned quite a lot that I did not know about my kitties. (They are my first cats as well, I grew up with dogs, but I am totally a cat lover now!) I love my babies and honestly if I could afford a grinder and the items needed to make my own healthy homemade cat food I would, but oh my gosh I looked into it and it is such a process, not to mention expensive for a high quality grinder! But still I am definitely going to look into at least getting my babies on a healthier and well balanced diet. I think Kino, my orange tabby, could afford to lose some weight too which I hope this new diet will help with since he'll be getting more nutrients from it and will be eating less and feeling fuller.
Here are some premixes:
