Fair point ... though it's more roaming on the road ... friend had near death injuries driving home one night and hit a black cow stood in the road (no hi-vis jacket or lights!! 🙂) ... bonnet just swept its legs out from under it leaving the half-ton body to crash unimpeded through his windscreen.
Our most destructive visitors are small herds of deer wandering through the garden ... they don't take fish from the pond though! 🙂
