I don't foster native animals, but will look after them until I can get them vet or carer help. I have on 3 occasions picked up quite young joeys from dead mothers when I have been cycle touring. Usually it seems in the middle of my ride between towns, and have prayed that they survive until I can get them help. I put them in a flannel pillow case I carry for the purpose, one joey was quite small and had to carry him in the pillow case inside my shirt, it was quite scared and it had to stay overnight with me and my dog as I had a long way to go. I would like to find a suitable way to feed them the appropriate milk( like a roo style powered milk) as it can be a day or more before I can get them to help. We, my wife and I have saved over 20 joeys of various species and all have survived to get them into care. I cannot go past a roo or any wildlife on the road without checking them.. This is the most painful part of travelling anywhere, as live out in the bush as well, and see it all the time. I applaud what this lady you named is doing..
