Any coconut oil that has "Refined" on the label won't taste like coconut. I get it at Whole Foods. Or you can buy MCT oil, which is the same thing, but no flavor (medium chain tryglycerides). I put some in a little brown glass dropper bottle so I can sneak a few drops into some Fancy Feast.
Got rid of hairball problem for my cat by rubbing a fingertipe amount of petrolum jelly on her leg every night. She licks it off and hairball problem and vomiting is gone. I went to a health food store and eveutally bought unpetroleum jelly as I thought it as better.
