my cat will drink out of the toilet if I leave the seat up but that is just because she is too lazy to go downstairs. I make sure to keep all the lids down now. I have a fresh flow water bowl and she has never refused to drink out of it. Actually, I am surprised at how much she drinks since I hear most cats don't drink enough water but she will drink any water, my gf brought over her dog (an akita) and I put some water out for him and all of a sudden there is my cat drinking the water and Max (the akita) came up to get some water and she hissed at him! Nothing funnier than seeing a 100lb dog scared of a 7lb cat!
