The SPCA believes a group of teenagers are behind a spate of cat shootings in Whangarei and have urged parents to take note before the situation turns more sinister.
As more pet owners come forward with complaints of slug guns being used on their cats, police have appealed to the public for information that could lead to arrests.
Onerahi police constable Spence Penney said complaints alone were not sufficient because there were no leads to start an investigation. At least half a dozen residents from Onerahi and Maunu have complained about cruelty to their cats but only a couple have gone to police.
SPCA chief executive Robyn Kippenberger said slug guns were mostly used by young people.
"The likelihood of these guns killing the cats is low but the likelihood of a prolonged death is high.
