<human>: Condense the text into a few key points

Hey everyone,

I don't know how to put the advice flair, so sorry in advance!

I just got a cat from SPCA (first pet ever). Took him (formerly Mariano now Rorschach) to my fair sized apartment and he is acclimating well! Not tearing up things, exploring well, being extremely friendly, and also eliminating in his new litterbox. 

Two things:

He has diarrhea right now  (I'm thinking due to stress and currently giving him florifauna or whatever it is called) and so I'm worried he's not drinking enough water when I am gone and barely drinks when I am home. I put a treat in two alternative water bowls to encourage drinking and that has been working to some effect. I am wondering if this is a bad thing? 

Also, near every food, water bowl and also after eliminating, whether he eats, drinks, or goes to the bathroom, he paws as if he is covering poop or pee (around water bowls and food bowl too) imaginary or real cat litter "over" the water and food bowl. Odd quirk? Or is Rorschach telling me something?
