Hi Jens
It’s good to hear that the school are talking to the children about the hedgehogs.
I wondered whether it might help, with the landlords, if you got some of the other tenants to, maybe, sign a joint letter asking for something to be done about the ventilation shafts. You will know better than I, whether that is likely to be helpful or not, but just an idea.
Just another thought, but if there are people there who would do harm to the hedgehogs, is it a good idea to get them too used to people?
Good luck.
