Edwina used to do this. But only in the powder room in the house we lived in before. I think she was too lazy to walk downstairs sometimes. (sigh.....) I always had to check the sink when company came over. I think I posted the story once of her getting in the sink while the realtor was showing around some potential buyers..... The realtor -- a friend and animal lover knew about her habit. She grabbed Edwina and said "Aren't cats so cute how they love cool surfaces!"

Once we moved she tried the powder room sink once but didn't like the configuration...

Although I would prefer it to the dining room carpet....
