We previously had cats who rarely seemed to drink any water - either from a dish or glass or plant tray, nothing!
New cat will hop onto a table and help herself to our water glass at any opportunity. I now keep a glass of water by the bed for her, for drinks in the night (she sleeps on our bed or nearby basket). She also laps at puddles in the garden :/
I'm assuming this is all normal, with the new cat. Do your cats often drink water?
