You are so lucky! My cats HATE HATE HATE WATER!! They are a docile breed that let me do pretty much anything too them, but they will not allow me to bathe them. They are Ragdoll cross / Ragamuffin cats (so I think, I got them from Craigslist) so maybe that breed is a non-water breed?
The funny thing is, if I am in the shower, my cats will follow me in and jump in with me and sit, but after ten minutes once they realise there is water they get out.
I have heard people say the reason cats don't like water is because they are "clean animals" and if they get covered in water, they basically have to re-clean their whole bodies with their tongue. Any thoughts on this?
