I have a 14 yr old cat who hates water. I'd like to clean her fur with a dry powder cat shampoo but am concerned about which active ingredients are safe and which ones I should stay away from. Googling for natural dry cat shampoo came up with a posting about someone who used some non natural product from the local pet store and it made her cats sick. So far I haven't been able to find a natural dry shampoo listed. Does anybody know of a nice safe product I could use? Or maybe a home recipe? Thanks very much.
