hope they make a speedy recovery mate
what ever it was the ferrets must have backed it up,iv bolted cats,stoats and foxes,with the ferrets they dont tend to stay around ,the smell of the ferts seems to worry them i dont know,i came to the conclusion that its a case of the hunter is being hunted!!!!
what does the bite look like ie ,space between teeth,puncture size?? any chance of a picture?
kind regards asme9
