I agree completely with you Matheous. Listening to the radio this afternoon, I understand the house concerned in which the baby was bitten had a damaged door, damaged enough to allow a fox to get in! Surely it would not have taken much to have made a temporary repair.
Foxes are now in towns and cities because there is so much food debris left around for them to scavenge.
But to leave a hole in a door, large enough for a fox to crawl through, this freezing weather with a baby in the house, to me, seems negligent.
