Sophie is now bring transitioned to pre-made raw diet NV and Primal medallions. My (limited) understanding of feline dental hygiene is that chewing on bones or dry food breaks up any build up and keeps their teeth healthy. But in the pre-made raw the bones are quite crushed. Will it still have an affect? Should I feed her some raw meaty bones a couple times a week also? I saw some "chicken necks and gizzards" at the grocery store. Would the necks sold at the store be ok? Not sure if they were organic though. I only brush her teeth once per week. What would be ideal for her new diet?
