The ears were a dead give-away in the first photo!
I found a dead one near my house last week. It had not been hit by a car and was a recent death as the ants etc had not taken over. It was so incredibly thin and emaciated, poor thing and looked as if it had succumbed to some sort of illness. Have you seen any others like this, Judi on your walks? So sad to see...
Do they have Myxie in Spain and if so, would it also attack Hares as well as rabbits?
