Hey there great to see you about on PT again, well my four are much the same, they drink more if on dry food for sure, i have six water bowls, three inside and three outside,four are ceramic bowls and two are stainless steel,one is positioned by the food bowl, one is on the stairwell, one outside on the verandah by the cat shelter, and the other two further around the front of the verandah one's and one upstairs in our bedroom where lexie mostly resides, one of my cats Ash, tends to drink right on the edge often spilling the water on the floor,the others are much more diplomatic about it,not making any mess, they also enjoy puddles, little monkeys, even though they have a good supply of fresh water daily.
Lexie seems to enjoy cold water out of the fridge.

Ash drinks alot because he has CRF, the other older cat drinks quite a bit, lexie also as she is on complete dry food, the youngest does not drink as much as the other three from my observations.
