We adopted Olive, the orange girl, four years ago. She had terrible baby teeth. So bad that we had to have many extracted - this was before she was six months old. She recovered and I didn't imagine her adult teeth would have problems but her breath became very bad and her gums were red. During a later trip to the vet, he examined her teeth and said they too had come in in bad shape. He said she would need another surgery and would suffer loss of adult teeth. Having very bad dental issues myself (DNA related) I was very upset! We wanted to avoid surgery. So we searched the 'net and I found Oxyfresh, bought it and added it to all the water bowls for both cats. And they are serious water drinkers. Bad breath was gone and remained gone. A recent visit to the vet for a routine exam showed no need for dental work at all. I wish every cat owner would try this product before they decide on dental surgery. Surgery is expensive, requires anesthesia and can be risky. Try Oxyfresh - just a squirt in every bowl and everyday day. My vet was astounded and I suggested he recommend Oxyfresh before surgery. The result was unexpected but amazing. It kept our Olive's fragile teeth are now healthy and it keeps our other fellow's pearly whites...well, pearly white.
