Is there anything I can get from kissing my indoor cat?

Yes. Toxoplasmosis and campylobacter to name a few bad actors. Cats are notoriously lax about washing their food, in fact, they often stick their noses in other animal's feces. They love to chew on mice and nuzzle dead things. May I suggest that you express your affection for your cat in the future with hugs and not kisses?
