@Bagardbilla People lying on the internet. What next, people defrauding the elderly?
And yes, you should stop using it on your skin, I think. I have general rule that I never purposely rub production containing petroleum distillates on my skin, it’s just seems like a bad idea but I was reading the WD-40 MSDS that @crisw posted a link to in her first comment. She’s right that it’s not going to hurt the cat to ingest small quantities but it indicates skin exposure, I would assume frequent and prolonged, is a different story and can result in defatting(medical) I had to look that up because I was sure what it was but it’s not good and can cause some pretty nasty looking dermatitis.
Edit: That’s one of those damn tricky wikipedia links and it takes you to the “degreasing” entry rather than the “defatting (medical) entry and I don’t know how to fix those but here’s another discussion.
