I haven’t owned a container of petroleum jelly in forever. I stopped using it forever ago on myself – in fact, I’m trying to think what I ever used it for. I know in high school I used it as lip balm, and at university I used it as a moisturizer before I went swimming (to keep the chlorine off my skin).
Anyhow, I bought some a few weeks ago to put on my cats. Yes, you read that right. One of the guys was having trouble with hairballs, and I read that if you put a bit of petroleum jelly on their fur every day, they would lick it off, and it would act as a laxative, to help them pass more fur in their stools.
(Now whenever I open the container, Guy goes running for the hills. Sigh.)
I appreciate simple (if unpalatable) fixes.
