My cat LOVES drinking from the toilet. If she sees me go to the bathroom she will stand outside the door and meow until I come out or if she hears the toilet flush from another room she runs in to the bathroom to drink the water, even if she has fresh water in her bowl. I've had to chase her out of the bathroom many times and teach my three year old and 28 year old boyfriend to close the toilet and the door so the cat wont go in. I have even caught her trying to push the toilet seat up to get into it. I've tried the water jug type bowls and putting fresh filtered water in her water dish but she still prefers the toilet water. I don't know if I should get one of the $20-30 nice flowing water bowls because I've tried to let the water run in the sink and she wont even try it... she is scared of flowing water except for in the toilet. She has never gotten sick from it before but I don't want her to get sick from any cleaning chemicals I use when I clean.
