do you have any vaseline or glycerine? (but pure glycerine, not mixed with any other cosmetic products)
i know vaseline is non-toxic because my vet told me it's okay to give for hairball prevention because cats don't digest it like lard or olive oil. wait, there's another thought if you weren't going to use it often: olive oil is great. i put it on my hair sometimes. or mineral oil? as long as it isn't mixed with scent like baby oil i think it would be fine.
