Ms. Hanson, in the Anchorage basin "private shelters" almost always means either "Mojo's Hope" or "Clear Creek Cat Rescue."  Five'll get you ten the cats to trapped and took to Animal Control were given to these TNR charlatans who promptly, and illegally, re-released them.  They keep their colony locations secret because the know their destructive outdoor cat-hoarding hobby is illegal.  Unfortunately Animal Control is lax at enforcing the law.  They allow Mojo's Hope president Shannon Basner to "volunteer" at the Anchorage animal shelter--she "rescues" such cats, meaning she "saves" them from euthanasia and re-abandons them outside.
