Five kittens have been dumped 300m from Wellington SPCA's Waikanae Centre.
They were found in scrub near a paddock, near an Electrolux vacuum cleaner box.
Four of the five kittens were just 6 weeks old and unable to fend for themselves. The fifth kitten, about 10 weeks of age, was found dead a few metres from where the box and other kittens were found.
The kittens are now in the care of Wellington SPCA, and the case is under investigation. Animal welfare inspectors are appealing for public help to identify who dumped the animals.
The Electrolux box containing towels covered in kitten faeces has been taken as evidence.
