As with any other substance, you reduce the pH of cat's food by adding acids -- vinegar or cranberry extract are commonly used for that purpose. The purpose of lowering the pH of a cat's food is commonly done to increase the acidity of the cat's urine, to help dissolve and prevent formation of crystals in the urine.
Acids reduce the pH of the food. If used properly, the pH will be reduced to a range where pathogens and many spoilage organisms will not grow.
Wrong question. If you change your cat's pH he will change it back - it's a mammal and is homeostatic with respect to pH. What do you really want to change?
ACID environment means LOW pH, if you reduce the pH it will be worse. Consider adding some base to increase the pH.
The pH changes in the urine so that the crystals are formed & then infection sets in. The pH changes to high in alkaline. You have to add medication to lower this to a more acidic level, that is why you must have a Veterinarian treat your cat. This usually comes from their diet. That is why it is so important to feed your cat a good quality name brand cat food. If your cat has blocked up once, then you should switch to a prescription brand such as C/D cat food. I think they also have a newer one out too. Ask your Veterinarian who treated your cat, what he or she would recommend as a good cat food.
Lower pH by adding muriatic acid.
If the pH is too high, above 7, drink sulfuric acid to reduce the pH level (neutralize the base).
Stephen curve is a graph plotted on pH level against time. This graph will show that the food intake will reduce pH level in the mouth to a level bad for teeth and then rises again with time.
Add acid.
Hotdogs are full of salt and have a strong smell and flavour, which would make it an irresistible food for a cat. However, a diet of nothing but hotdogs is unbalanced and extremely unhealthy for a cat, as it does not have all the nutrients a cat needs. It is highly advisable to reduce the hotdogs to occasional treats, and stick to a high-quality cat food for the main diet.

pH and Alkalinity/Acidity are functions of each other. pH's above 7.0 are considered alkaline and pH's below 7.0 are considered acidic. So reducing the alkalinity will by it's very nature reduce the pH of the pool.
No a cat's pH is totally different from a human's http://www.adelaidevet.com.au/can-i-bath-my-cat
