Just thinking a bit more, some of our neighbours cats have been attacked recently and left with strange bites and abcesses. Ours was similarly bitten badly just over 2 years ago and we took her to the vet for treatment; we thought given the size of the bite it must have been a fox but the vet said not. It was definitely not the jaw size of a standard cat nor did it look like a fox bite. He couldn't identify it as a dog bite either so the potential cause was left open ended and we thought nothing of it but now it may be possible it was one of these animals. Our cat wouldn't venture far at night and we know the dogs locally are usually locked up and probably would be too scared to go for a cat anyway so that sort of ruled them out. Foxes dont tend to bother with cats unless they are weak or they go near their cubs but it was out of cub season. Anyone else have similar experiences with their pets?
