Iams dried cat food good or bad?

I would recommend a mixture. My cat has a healthy diet and lots of energy he is fed felix, whiskas and go cat dried biscuits. I alternate between them because like humans i believe variety makes food more interesting, it also makes them less fussy- as we know cats can be very fussy. I would recommend that you get the vet to clean his teeth occasionally and you can get special toothpaste, i got this from my vets and my cat doesn't have smelly breath or yellow teeth common with many cats.
