Well the meeting online took place, but apparently descended into yet another 'bunfight'. The owner joined in and said she hadn't got a solution, but felt unable to move BamBam to another location. She was subjected to a lot of abuse, which I think is wrong. Abuse is never, ever acceptable.
I think she feels very maternal towards the deer and has brought him up from a tiny vulnerable fawn. In effect, she truly loves him and he loves her. Having loved many cats over the years, I can relate to her feelings. But I just hope and pray that there won't be a dreadful accident in which either the deer or a human gets badly hurt or even killed.
I didn't join in 'online' but neighbour-across-the-road told me all about it this morning.
