I apologize for the lack of carriage returns;for some reason the forum software doesn't recognize them coming from my laptop. At first I thought he just had a bit of dirt of fluff on his whiskers, but upon closer inspection, his whiskers were actually singed. After that I found the cord he chewed through.There is a small bead of copper on each of the wires he exposed, indicating that there was at least one arc. I don't know when he actually did this, but it was probably this morning. I called the vet, and he said that as long as the bun is still eating and drinking,he's OK. I confirmed that he's still doing both of those things;he ate a grape and hay without hesitation, and he also took his neutering medication without hesitation. Of what I could see of his gums (just the area around the big choppy front teeth, on the side of the singing), there is no damage; they are pink and there is no bleeding. There does not appear to be any singng of the fur,either. He is licking things, mostly cleaning himself. He's been laying down (not bunched up in a corner) for a good while this afternoon. Hmm. It's possible that he might have gotten a mild shock, and a few current spikes through the whiskers (the whiskers are not singed at the base, implying that current did not travel into his lips). I'm not prepared to say that he was acting funny today, because if he was it was such a subtle difference that it could be my imagination. It's possible that he sustained only whisker injury. Is there anything else I can check to asses bunny damage? So tomorrow is bunny-hardening day. Wire loom from the auto store, I guess. We had thought we'd done a reasonable job of bunny-hardening already, but it was clearly inadequate. I plug my laptop in at a spot where I cannot see a length of the cord, and this is what was chewed. I believe he chewed it while I was sitting right there, or while I had stepped away for a moment.In any case, dodging a bullet is no cause for celebration.
