There is a product called Solumel made by a company in the States called "Melaleuca"; they also make an antibacterial soap that is the best I have ever used. Oil Of Melaleuca (Tea Tree Oil) is good for removing oil and tar, without the harsh chemicals in soaps and solvents. These are natural non toxic remedies, the natural oils in the cats fur will recover faster if you use them. Yours, Aye. Dave (The ancient horse farmer)
