You sound very handy Jon. Great that you've adapted your bathroom for your needs.
Our little spoiled horrors always have a lovely stainless steel bowl of fresh water, washed out and re-filled several times a day. But they much prefer the tap (and our water is very hard and chlorinated) In summer, they'll lap water from a manky puddle in the garden after it's rained.
I actually miss the old levered taps, (so easy to open and close) but we've long since accepted that we're under the control of our Siamese masters...
