If you're a vegan then you will understand even better why it's important to make your own food for your cats. If you think the meat industry is bad, you should dig around in the pet food industry:
https://truthaboutpetfood.com/. Aside from the incredible health benefits to my cats, I feel very strongly about not putting any more money into the pockets of these global conglomerates who control what our dogs and cats eat as well as what our veterinarians tell us to feed.
Yes, locally sourced, grass fed and cage free will be more expensive. But if you're willing to forgo that, and go to the supermarket to buy meat, you can probably save yourself money. For example, my Ruby needs about 8 lbs of raw meat a month. I could go to the supermarket and get organic chicken thighs for say $5/lb (I'm guessing here at what it would cost in your area, it might be cheaper) and mince it up with a cleaver or grind it up in a food processor. That's $40 per month. Add in the cost of Alnutrin with egg shell calcium ($15/bag that makes 16 lbs of food), some liver and fish oil, so you can probably feed one cat for less than $50 per month. I would spend that much buying her a month's worth of high-end, good quality commercial food, and I think about how much money I save on vet bills if my cats are healthier as a result. Dr. Lisa Pierson has a whole thing devoted on her site to making your own food including food safety that I learned a lot from:

That's my raw feeding speech.

You have a lot to think about, so take it all in slowly.
