Meh is very pretty and very photogenic! It's cool to have such a set of pro pictures!
Sorry to read about the health issues but I've learned that our cats also don't drink enough when there's no running water.. they always insist on drinking in the bathroom sink when I go there, lol.
The smart and logical thing was to get a fountain. Luna loved it, drank much better but Maesi always needs to push the thing and hit it with her paw until the lid comes off. The second fountain we bought was better but still at night she'd break it open and the whole hallway would be wet as half the water came out in the process..
Right now I just accepted that I have to just let them drink from the tap instead lol..
Maybe that's an idea for Mew as well in case you don't already have that?
Hope you have a good weekend!
