According to a report released on Sunday, a nonprofit organization was tasked with the shelter and care of the city's unwanted and stray animals.

The organization has come under fire again, and this time for alleged ineffective oversight of drugs used in the treatment of pets and for overcrowded facilities.

As per the auditors for New York City Comptroller Scott M. Stringer, the city's Animal Care and Control doesn't maintain a computerized inventory of drug usage, instead is relying on handwritten logs.

The report said that over a four-month period started in December 2013, the organization has failed in accounting for 239 tablets and 43 bottles of many controlled substances, including drugs like Telazol, an anesthetic, and Tramadol, an opioid. In addition, some of those controlled substances, which had expired, were 'easily accessible' to employees.

Proper maintenance of a computerized inventory of drugs was a condition of the organization's $51.9 million contract with the city's Department of Health and Mental Hygiene.

At a news conference on Sunday, Mr. Stringer said, "Animal Care & Control is providing neither quality care nor proper control over many of its operations. What we found was a disaster waiting to happen, for animals and staff alike".

The audit found that besides, using expired controlled substances, Animal Care & Control also stored some of its vaccines improperly.

The report said that auditors, who visited the city's three shelters, have found a number of issues, from peeling paint in Staten Island to overcrowding so bad in Manhattan that animals were kept in kennels lining a hallway.

The organization in a statement said that it has already undertaken steps for the implementation of several of the recommendations in the comptroller's report.

The company has also mentioned that it will continue to strengthen their policies and procedures to ensure optimum performance and the best possible care for our animals.
