A family cat cut into pieces and a carabiner threaded through the neck of a dog are among the most inhumane treatment of animals on the SPCA's annual list of shame.
There were more than 30 "grievously inhumane" acts on the list and each was an indicator of someone who was likely to be violent towards other humans, SPCA chief executive Robyn Kippenberger said.
The cruelty towards animals continued to shock the SPCA, which recently released research that showed a strong link between animal cruelty and domestic and family violence, she said.
"The sheer level of violence meted out on animals by some of the perpetrators in the cases in this year's list of shame is shocking and underlying of wider issues in New Zealand."
Ms Kippenberger said the list, released by the SPCA today, was full of examples that were "all too familiar" to SPCA workers who were tasked with the "heartbreaking job" of deciding if an injured animal should be rehabilitated or euthanised.
