We keep the seats down, also, so no toilet tipplers here.

We do, however, have a gallon pail of water in the tub in the hall bath - just in case there is a power failure and we need to flush. Living in the country, we have a well - so no power, no water. The cats love to get in the tub and drink from the pail. This technique has been passed down from cat to cat for the past 10 years.
