I purchased a new bigger tub of petroleum jelly as all my cats will take that nicely for hairballs and such. Well I opened it tonight and gave a little bit to one of my cats. Then noticed a smell to only realize it was the Petroleum Jelly! I didn't see it labeled because they wrote it so small on the label! Just wondering if this will harm him? The only ingredient listed was the petroleum jelly nothing else So I don't know what else is in there to give it the scent. I'm hoping it isn't going to make him sick! Anyone ever give their cats a scented petroleum jelly?
