Are you trying to get a spare hutch?! :lol:
Maybe Lol no, just showing my admiration...
Even if someone did offer me a hutch Mummy would say no :lol:
Really? Wouldn't she take a donation?
What about a free one? Have you had a look on your local freecycle?
If you did manage to get a hutch you could paint it green to make it blend into the garden and your Mum wouldn't notice it so much. Even a small 4ft one would be nice for your baby at the moment espeically in this nasty weather.
I know you don't get on with your sister but can't you try and get her on your side? She could approach your mum for you? Green shed paint is really cheap now as well.
Just thinking of the tatics I used when I your age
