CRASH Hedgehog Hospital- New shed

CRASH Hedgehog Hospital is a registered charity, founded in 1992. We urgently need a replacement outbuilding for the sick, and injured, adults and orphaned baby hedgehogs. The original one is now 25 years old and the floor has rotted and the shed is collapsing.
Most of the hoggies have had to be moved out, but the babies are too small to be put in outdoor hutches so are now in cages all over the house!
Things are getting desperate now, so we urgently need another insulated shed or outbuilding to house them in. In the meantime  it's getting difficult  to admit anymore patients as I have no room to house them.
We will need something insulated and with electric sockets etc for the heating and lights, glass opening windows for the hot weather and a secure base to support it. so the cost could be enormous. Anything you can donate would be of real help towards it!
In the 25 years CRASH has been operating, we've never turned a hedgehog away that needs help, and
I really don't want to do that now!
Please help us to get a replacement as quickly as possible.
On behalf of my "Prickly patients" and myself. Thank you!
