We've had our rescue cat for about 7 years (adopted as an adult so likely 10 ish now) and he's developed thyroid issues in the last year or so, but these now seem well controlled by his medicine and he otherwise seems well. Recently we've noticed he's been drinking from the water droplets in the bath after we've showered in preference to his water bowl. It goes without saying that water is fresh and the bowl clean. I'm not sure whether this should concern us or whether it's just a new fad (in which case maybe we should just buy a china bowl for his water to see if he likes it better than the metal one he has. I looked at cat water fountains but they all seem to be plastic - and expensive!) Since the repeated blood tests for his thyroid issues he loathes vet visits and gets very stressed so we prefer to avoid them unless absolutely necessary.
