I have to say I've joined this group and I'm really impressed with their organisation.. and no one has tried to sell me anything!
They do have a doggie bias but there are cat people there, and rat and rabbit peeps too.
They have a database of volunteers across the country, listed by county, who are willing to help with transport and home checks as well as fostering. Basically, they all seem to be volunteers for existing rescues who don't mind helping out another rescue or different kinds of animals than they usually do. The forum lists special cases were transport is needed fast to save animals from PTS to rescues who have agreed to take them. (How many times do we struggle with things like that!
)
Anyway, I expect Tan will form her own opinion but I can see this being a great resource for people here too.
