My cat sometimes drinks from the tap?

My cats used to drink form the toilet there is no harm done to them bey drinking from the tap. but it is very funny when the kittys fall into the toilet. K/C the cats are pprobably drawn to the dripping water, there is nothing to worry about unless u get ur h2o from a 100 yr old well, or live in an area with high levels of lead of asbestos in ur h2o, and in that case u shouldnt drink out of the tap either and u both should be using bottled water.
