They hide key info on their website

Important information should always be made public and available to anyone when viewing the website of an animal shelter. In other words, their address, email address, telephone number, and so on should appear on their official site. “If listed as operating by appointment-only, that could be cause for concern. If invited in, be sure to request a tour of the facility or foster homes,” said Dr. Hansen. 

According to Dr. Jeannine Berger, vice president of rescue and welfare at San Francisco SPCA, every animal shelter should follow a mission statement. “Do they follow their mission statement, and do they have any information on welfare for the animals in their care?”
