Holy crap! Poor Buster . . . he could have lost an eye! I'm glad he'll be okay.
A few months back, the Dread Boston Salty tangled with the possum under our deck. Thing had to be 12 pounds, and it scratched hell out of Salty's head and bit him on the chin. He had a puncture and quite a few scratches, so we rinsed him off in the tub and Bactined him up.
We were most worried about his left eye, which had gotten scratched, but it was a very minor scratch and was mostly gone by the time we got to the vet.
Yikes! Possums have a mouth full of sharp nasty teeth! My dogs used to chase them when we lived near Dallas, and one time they cornered one. I was there and made them stop, but that darned thing looked like a tasmanian devil with all those teeth!
