“No one will be held liable, or be in trouble for abandoning the cats, but we’re hopeful the responsible party will get in touch with us to provide the needed information,” HMS said in a statement.

To help alleviate overcrowding at the shelter, they are waiving adoption fees for all adult cats until the end of September.
