Online classified site Kijiji says it has no plans to stop breeders from selling animals on its site despite a two-year-long campaign against the practice.

Montreal-area librarian Barbara Lapointe has gathered more than 104,000 signatures on a petition asking Kijiji Canada to stop allowing pet sales on the site and encourage only adoptions from registered shelters and rescue organizations.

Lapointe says the current policy allows venders to turn tidy profits by selling pets produced in dog or cat mills and other unsanitary, mass-production facilities.

Letters sent to Lapointe show that six companies, including Toyota Canada and two of the country's major banks, have supported the campaign by pulling their ads from Kijiji's pet sale pages.

She says Craigslist and other classified sites have refused to allow breeders to post ads and argues Kijiji should follow suit in order to protect animals.

But the company says it has no plans to stop hosting animal sales ads, arguing that banning such posts would not be an effective way to stop animal mistreatment.
