Cat owners... what do cats drink?

Sounds stupid but there's been a cat 'visiting' me (when she's hungry, don't think it's owners look after her very well :( ) and I've been feeding her all sorts (roast beef, turkey, tuna, even bought some cat food) but she doesn't seem to drink the water I give her (someone told me cats can smell the chlorine used to clean the water so they don't drink it!?!?) She likes milk but I've been told it isn't good for them, gives them diarrhea?!?!

What do they drink?

Any way to tell if she's pregnant?

She's not been spayed (I spoke to her neglectful owners... bastards) and she seems to be eating and sleeping alot, becoming very chubby around the hips, typical lady ;) hahaha

Any way to tell whether she's got kittens brewing within? A cat pregnancy test maybe? :) ?
