I use Brita water for my kitties. Many years ago, I had a roommate...she had two cats, I had one. I had a huge room as a bedroom, so kept Dave in there (the cat). I would let him out occasionally though, and he would make a beeline for the other cats' water dish. I told Dave he had water already...my roommate then said that she used filtered water. She said cats like it - it tastes more like rainwater cause there isn't any 'people additives' in it.

There are generic pitchers and filters now...some pitchers that are in great shape can be found in second hand stores. I just wash them with hot water, soap and some bleach, and rinse well. They work great.
