>>Animal Control Departments have public records that may hep, such as the number of registered animals, numbers of surrendered animals, numbers of abused,neglected animals that have been reported or cited, and number of complaints considering pet dumping and feral animals.

Ohh, I know that. But the shelter intake records are never going to tell you about all the animals that are dumped out in the country and never make it to the shelter. That's why I was interested in seeing if you actually had any data behind your claim.
