Apple Cider Vinager?

I've been wondering about this ACV for my kitty. I've never used it and always gone for the brand names in fleaing my animals. How much do I put in his bath? (my cat actually LIKES a bath. Weirdo he is)

And how much do I put in his drinking water?

Apple Cider Vinegar helps Pets with arthritic conditions, improves digestion, increases resistance to diease and gives a beautiful shine to their coats! Use only raw, unpasterized, unheated, organic apple cider vinegar as it contains vitamins C, E, B1, B2 and B6, minerals and trace elements found in apples. Vinegar is also great topically to control yeast infections on the skin and feet. Mix with equal parts of water in a spray bottle and spray onto affected areas or add a splash to unscented baby-wipes or use as a rinse after a bath. Oral Dose of Apple Cider Vinegar is ½ tsp per 15lbs of weight.
