Thanks for the info Phred! I'm most definatley going to be on the lookout now. I'm also going to try to change a few things, from now on the kitties are only getting bottled water. I'm also going to reduce the treats since i know they aren't very good for them, and I'm thinking about switching them over to a healthier food. They are on science diet right now, so I might switch some something of higher quality.
