Hi Love Foxes don't actually leave the family group until forced (usually by vixen having another litter). If it was a fairly young fox then the other fox was probably its mother or a sibling. They will wait until it is cold and stiff and then they will leave it. Never knew you preferred animals to humans - I'll tell Jake (who has three puncture wounds less than a centimetre from his carotid artery but apart from that is just dandy). Rag
