State of the Jazz: reason to be concerned?

Jazz finally horked up a large hairball she'd been "working on" since Monday morning yesterday. Since then, her appetite has been a bit off...

She'll eat, but instead of taking her about 15 minutes to fully eat her allotted portions of food, it takes her at least a half hour to an hour. Sometimes she doesn't quite finish her meals, either. And tonight she barely touched her final feed. This is with the appetite stimulant on board twice a day to help enhance her appetite, too...

I'm concerned but not freaking out just yet. She's still eating, albeit slowly, save for her final feed tonight. I just presented her bowl to her again to see if she might eat a little more...

If she's still putzing around with her eating tomorrow morning, a call to Dr. B is in order. I hate to have to bring her into the vet during this nasty heat spell we're having, but if he wants to see her, I guess I'll have to do what I have to. It's supposed to be cooler on Saturday and we don't have anything going on so perhaps we can wait until Saturday morning to bring her in.

Dammit, the last thing I need to worry about is Jazz getting sicker! :( Please, Bast, let it be nothing, or, barring that, something minor that's easily rectified!
