Oral hygiene, questions

I have been reading (this site) on oral hygiene, and Logic Gel in the UK. I have a product called C.E.T. enzymatic dentifrice I have had for years with the intentions of brushing my cats teeth. Never did, but some of the threads say they just put it on their paw, and it works. Is this the same product? Can I use it that way. oh, it expired in 10/06. Active ingredients are monofluorophosate (0.18%), Glucose Oxidase, Lactoperoxidase. product of virbac.

Will this affect urine PH?

I dont know about the product but I wouldn`t use the expired tube if I were you. It would probably be ineffective or it could even be dangerous.
