Ok guys, dragging this one out because of my Tony. I woke up this morning to find 2-3 dark chocolate Dove Promises scattered about the couch, including shredded wrappers. This is approximately 16g of chocolate.
After examining the bunnies and knowing Tony's personality, it seems he was the culprit, not Muffin. He had a bit of a stomach gurgle upon listening to it (I've gotten pretty good at holding a bunny's tummy up to my ear and listening). No other signs except that neither bunny was too excited about veggies this morning. I examined their gums, heart rate, pupil dilation/response to light, breathing, and poop, and all seem to be normal.
I gave Tony 1.5 mL of baby simethicone for the gurgles. They seemed to be less frequent a few minutes later when I listened again. Granted that the bunnies may have eaten them up to 12 hours ago right after I went to bed, and there are no symptoms, can I assume that they don't need an emergency trip to the vet? I will be pushing greens and hay in their faces so they eat them and keeping a close eye on them for any change.
They've really gotten a lot better at jumping onto furniture in the new place and finding things they shouldn't (first the remote that wasn't chewed on before, now this)..
