My Siamese, Sable, likes to drink from the toilet, too. Problem is, there’s something in our water that gives her the itchies. My barn cat, Diamond, is unaffected, so it’s got to be the water that makes Sable itchy. (No, not fleas. But maybe, Siamese being the feline equivalent of Arabians, it’s just brain damage…:lol::lol:
I give them both distilled water. And I keep their water bowls clean. They’re cleaned every day. Some folks never, ever clean a water bowl and the scum that develops must taste bad.
In most parts of the US, there’s a low level of arsenic or selenium in the groundwater. It’s just there, there’s nothing you can do to remove other than go the route I did, having a whole house water filter installed. Even so, Sable has issues with the house water. She’s fine on distilled. The advantage to that is when we travel and take them with us, they will drink the water because they are used to distilled.
Both my cats are absolutely fascinated by a dripping or dribbling faucet. They’ll sit all day, just watching the water fall.
