The SPCA says more than 200 pets are still missing in Christchurch following last month's earthquake.
In the aftermath of the 7.1 quake, 445 pets were registered as missing, 409 of them cats, the association says.
Many found their own way home or were reunited with their owners through the association and other organisations.
SPCA national president Bob Kerridge says it is tough for people who have not been able to find their pets, but owners should not lose hope as many pets will take some time to come home.
Pet store Animates has launched an earthquake fund to raise money for the SPCA and the Cats' Protection League.
