Liquid paraffin during moulting season: how much and how often should I give it?

Hi everyone,

With the moulting season in full swing, I’ve bought some liquid paraffin for my cats (recommended by my vet to help with hairballs) but I’ve got absolutely no idea how much to give them or how often. I’ve tried searching online, but I can’t seem to find these details anywhere... Does anyone here use it, and if so, in what dosage?

I know there are other products available like malt paste, but I’d really like to try this oil as my vet suggested it, if possible of course.

Thanks in advance!
