Hi, I took my cat for his booster vac's/check up this week, and was surprised by the discolouration of his teath. He is 2 years and 2 months old and was hoping if anyone has any advice on preventing this from getting any worse. I should have asked the vet at the time but it wasn't my usuall vet and for some reason this put me off. 
I had been feeding him 1 Felix pouch a day(in the evening) and Whiskers biscuits which he has access to all the time. I knew this wasn't the best for him but didn't think it would cause a noticeable problem so soon.
I have ordered some Iams biscuits to replace the whiskers and also looked at various suppliments that are ment to help with dental health. Has any one used these and if so are they helpful?
Any feed back would be greatly appreciated, thanks.
