I have a barn cat that has gotten into oil. I’m not sure what kind but it is oily to the touch and smells like oil. He must have jumped into something with it because he is covered half way up his side, his whole lower half is soaked. I got a big plastic tub and filled it with water with Dawn (tub is only six inches deep) and was able to get him in it. Some of it came off but not near enough. Can you think of anything else I can do to help this little fellow? He has long hair and is now the most pitiful looking thing. Thanks!
