Cats are sensitive to a protein in our earwax so they find it appealing. I had a cat so obsessed he would hunt down my ear plugs (I had to put child locks on the bedside table drawers). Occasionally the earplugs would fall out in the middle of the night. One morning they both fell out and I grabbed one and thought I may have accidentally dropped the other. My cat raced in out of nowhere and I chased him away but I couldn’t find the plug. Fast forward twenty four hours later and I found a full ear plug in a pile of vomit. Thank goodness he was ok, but that damn cat zoomed in and swallowed that earplug whole in a millisecond and it makes me laugh thinking about it to this day.

Cat seems to like strong body smells, we had an amazing cat when I grew up, completely black, short but very compact fur, with tuffs of hair on her ears, she was a mix between a siamese, norwegian forrest cat and swedish farm cat, she was an amazing huntress as well she caught a lot of annoying fieldfares snd mice, even came home with the tail of a squirrel once....

Anyway, she really liked the smell of my toenails and would even lick the clippings.

I wonder why....

She also LOVED my moms home made apple pie, she could resist meat, fish chicken and other stuff like that being left out, but apple pie... she just would not care and go straight for it, even if we were in the same room and she knew she wasn't allowed on the table, that was the one thing she was obsessed with...

Cats love ear wax. With one of my cats we get wax out of her ear and let her lick it. I think it's the protein.
