I just discovered that a guy won a science prize (though it's the Ig Nobel) because he scientifically proved that cats were, in fact, liquids. I think I heard it somewhere before, but I didn't know it was an actual thing.
Now I just can't stop thinking of concepts for liquid cats characters and want to see more of them (only thing I could find was a game called Cats Are Liquids I remember playing but it's more oneiric than anything).
