I used to work at a humane society and our animal control would take welfare calls quite frequently and go out just to check on a situation. If the address posted on the other forum is correct, Wyandotte Animal Control would be the first ones to try (and if they aren't the correct party they should be able to direct you to someone who can be of more assistance). Here is contact info I found on Petfinder
