Wouldn't it be better to relocate them to an unpopulated area? Trapping and relocating is quite common with wildlife that invades a residential area (on the other hand it is probably the residential area that has invaded the wildlife's domain). But I think they would be much better off, in the wild, than taken in as a pet. Some wildlife is not meant to be kept captive.

I hope she will consider doing that, rather than shooting them! How horrible!!!
