The Toronto Humane Society's adoption blitz is ending a day early after the last animal at the shelter was adopted Saturday afternoon.

The Humane Society's River Street location will now close its doors until June 1 for a court-mandated restructuring of the organization.

Ian McConachie, spokesperson for the THS, said the revitalization effort will officially begin at 7 p.m. Saturday.

"We are excited to take this time to improve our operations and come back stronger and better able to serve the animals of Toronto," he said in a news release Saturday evening.

"This short-term closure will reap long-term benefits for the Society and the thousands of animals we help."

Animal lovers looking to adopt a pet can visit the Humane Society's Victoria Park location inside the Van Horne Plaza at 2802 Victoria Park Avenue. McConachie said the shelter has 16 cats available for adoption.

That location will remain open throughout April and May, or until all of the animals have been adopted.

The court-ordered closure comes after months of legal battles with the Ontario Society for the Prevention of Cruelty to Animals.

The OSPCA launched an investigation into the shelter in June 2009 after the Globe and Mail investigated the Humane Society's restrictive euthanasia policy.

Eight senior employees at the THS were charged with animal cruelty after a highly publicized raid at the River Street shelter in November.

A lawyer hired to represent the THS board members facing animal cruelty charges has suggested the acrimonious history between his clients and the OSPCA drove the raid.

In the aftermath, the OSPCA displayed a mummified cat that had been found in a live trap in a ceiling.

It claimed that 25 animals had to be put down and numerous others were showing signs of neglect. One senior OSPCA official described the shelter as a "house of horrors."

The THS has filed a court action of its own. It accuses the OSPCA of negligent investigation, trespassing and defamation.

Tim Trow, who headed the THS from 2001 until 2009, resigned from the board of directors in January, nearly two months after he was charged with two counts of animal cruelty and three counts of obstructing a peace officer.

Trow's lawyer told reporters at the time that his client still intends to "vigorously defend himself" against the charges.
