What to buy with raw to keep teeth strong/when to feed and how much?

[whatsupRT02]

So I know cats need to chew on harder things with their raw diet to scrape plaque and keep teeth strong. What do you all buy for your cats to accomplish this since you can’t mix kibble? In addition I work 12s and am wondering if raw will work if I can’t feed them during that time(I know 3 meals is what’s desired). Anddd how much do you feed daily per meal. I am looking at Darwin’s currently. Let me know what you guys think about my big list of questions here! First time sphynx kitten owner so shoot away

I usually freeze-dry the chicken neck or raw rabbit ribs to clean my cat's teeth, besides, I insist on brushing his teeth every day.

I feed it three times a day. At 7: 00 a.m., 6: 00 p.m. and 11: 00 p.m.(It usually sleeps at noon and has no eating habits. Of course, I also have an automatic feeder in case of emergency.)
