I HATE the question of what's best. It's like, you don't want to be kicking yourself later for making the wrong decision, but you have no idea what the wrong decision is. It sucks.

I've decided I have become overly obsessed with my cats' behavior. I'm paying way too close attention and I feel like nothing they do is the right thing... Brindel slept for two hours, that's wrong; Pele waited longer than usual to get in the litter box, that's wrong; they're both drinking too much water, it's all wrong!!! But if the reverse of each of those were true, I would think it was wrong too. Overkill!

Can you call your vet for advice?
