Tsoomi never cleans anyone, as he hardly likes to clean himself... Milki ad Kfitzi clean each other often since they were kittens (they are half brothers...same daddy). Gucci only cleans his friend Kfitzi ... he hates Tsoomi and he ignores Milki...
I have a video clip in my website of Gucci cleaning Kfitzi - I thibk it's really sweet!
