My Princess can swim like a duck.
She manages to squeeze her fat butt (and legs) in the transparent water bowl, then starts paddling with her lil feet
The first time she did it we were in stitches lol, we thought it was a one-off but she actually does it often.
I guess it's a form of exercise

Note: the feet don't touch the bottom of the bowl because she is too fat to completely get in, and it seems like she enjoys it very much!
