Hi,
The RSPCA is not allowed to release squirrels (gery) once they have been caught as they are not native to this country and are therefore classed as vermin. As for foxes they do have wildlfe centres and are in contact with other wildlife organisations, so if the animal recovers they will release it, if not and it would not be able to live wild, then they will destroy it. Pigoens I am not sure of, but they are also classed as vermin so probably, and mujack deer I have no idea, again they are not native to this country. I used to be an RSPCA volunteer, but I disagreed with some of their policies,albeit they do it for the greater good and without malice, but it made me resign. I now support the Dogs Trust., WWW, the dogs home battersay and PDSA and Blue Cross as their views are different.
