The other evening we shot a vixen that looked pregnant. Wanting to know if it this was correct or not, we cut her open. There was no sign of foetuses (foeti?), however, while we were investigating a nasty looking worm appeared in the middle of her guts - it looked like an Ascaris lumbricoides-like thing, about two and a half inches in length with a long tapered head end. I'd be most grateful if anyone here is able to tell me what it was likely to have been!
