A little backround: We’ve had some trouble with water damage and mold in the old bunny room since this Spring. We’ve had a very dry late Summer/Autumn, so I decided it wouldn’t be harmful to keep the bunnies in there again.
Well, I didn’t notice it, but apparently, the mold came back…and the bunnies – who have a habit of tearing loose pieces off the wall – chewed off a really moldy patch. 
I’m not sure which rabbit did it, or if both of them worked on it. However, Mr. Bunny has been in that room since this morning, and he might have done it. I’m not sure how much he ate, or just how moldy the paint layer was. But I’ve read about how dangerous mold is for bunnies, and I’m scared to death…
Mr. Bunny seems relatively normal. He’s a little sleepy (not unusual for him at this time of day), but he seems to have a full appetite. He hasn’t made much poop today, but that’s also not too unusual for him – and I heard gurgling, so I know he’ll be pooping soon.
Should I be concerned?
