No dental problems
My three cats have had some form of fibrous dry food for several years now. I turned to Sanibel because the 10kgm is about the samer price as the 5kgm pack of the food they were then having. There has never been a problem with acceptability, the cats love it. Their annual check gets only a 'thumbs up' from their vet, who says that their teeth are in good condition for their age.
I feed them twice daily, Sanibel Dental in the morning, and an alternating dry food in the evening. As a treat, they have wet food from can or pouch, but really seem to prefer dry. None to throw away, either; it all gets finished.
