More than 300 cats have been rescued after they were found living in a single apartment.
Pictures from inside show dozens of animals sitting on every available space, from the windowsills to the stairs, toilet and kitchen counter.
Its a terrible way for cats to live, rescuers said after posting the images on Facebook.
Unsterilised cats breed prolifically, and with only a nine week gestation things get out of control VERY quickly.
Toronto Cat Rescue described what they found in the flat as a perilous hoarding situation.
