i've never seen one so i'm not sure...i'm asking because, though i keep an eye on her as best i can, my kitty has started to gain interest in the large turtle tank i have in my living room that i've witnessed her jump on top of (there's a small area of plastic she can stand on)...i don't plan to leave her unsupervised but if she should jump in while i'm turning my back one day..would she drown? i know there's no guarantees and i keep discouraging her from doing it..but i was wondering what her chances would be if it happened one day..so anyway, can they swim if they need to?
