I went to Petsmart to find a new bowl. First, I still find it EXTREMELY strange that Koji used to drink like this, but Miko didn't. Now Miko does and Koji doesn't. Strange little boys.
Anyhow, my biggest concern was Koji drinking down the water so that when Miko would drink, his tongue just wouldn't hit anything. Especially during the day when I'm not home. And if you recall, Miko has kidney failure, so he needs the water (sorry, can't do broth, and he gets home cooked food, so he actually gets a lot of water in that, but still drinks a ton).
So, this is what I bought them:

I wasn't sure at first if Miko would like it. Although, it was hilarious, I had moved it about a foot from where his bowl normally is and picked up the old bowl. He walked over there later, staring at the spot, like, where is it? Then saw the new one. LOL
He seems to really like it. I mean, he's still drinking from the side, but with the big water container in the way, he seems to get his face just a little bit more in there, which means he gets water faster. AND I don't have to worry about the water getting to low since it's in that huge container (holds 1 gallon). You can even put a filter in it (we use filtered water anyways, so I'm not buying it).
Thanks for all the suggestions everyone. I think this may just work.
