My husband offers his earwax to my cats, two of whom seem genuinely to enjoy the stuff. Yuck. I find this very troubling and worry that he’s also picking stuff from his other orifices and allowing the cats to lick that stuff, too. I tell him I prefer he keep his bodily discharges to himself and not offer them to my cats, but he finds it hilarious and sneaks my cats these disgusting offerings anyway.

Two questions: How do I sensitize my husband to how objectionable I find this? And what is it about earwax that my cats seem to crave?
