My pets have had a problem with fleas ever since we got our cats that go in and outside. Flea medication is expensive, so my dad was looking for a way to get rid of fleas, cheap. He found this site that said if you put a little vinager in the water, there will be no more fleas. I checked my cats and dogs this morning, and there is no fleas on them ! This is a very good home remedy. Does anybody know why it works? All I can figure is that it makes the dogs (or cats) taste bad.....
