I heard thumping around upstairs so I came up to investigate and found my cat Sugar convulsing next to a space heater. When I got close to him he jumped across the room (it reminded me of those cartoons when a character ricochets off stuff) and hid under a chair. He was no longer convulsing and just seemed nervous and wanted to be alone. We left him for a few minutes to calm down (by then I had discovered the source of his convulsions: a chewed wire near where his head had been when I discovered him). I picked him up later to examine him: he was nervous but let me carry him. The only physical damage I saw was a little red on or in his nose (I can't tell if the blood is from a burn or cut on his nose or if his nose bled from the inside) and of course his anal glands had released so his bottom was wet and stinky. I carried him downstairs to give him some of his favorite canned wet food and he seemed to perk right up after he ate. He is eating, drinking, behaving, and breathing normally at this time but I will keep observing him for signs of burns or internal damage.

My big question: Should I take Sugar to see a vet right away to make sure no damage has been done, or should I just keep tabs on him from home? I've never had a pet electrocute themselves before.

Needless to say I will be diligent about keeping him away from wires and will unplug unused appliances. This hasn't happened before and will see to the best of my ability that it doesn't happen again.
