The SPCA are calling for information after a mother cat and her kittens were found abandoned at the bottom of Mt Messenger in Taranaki.
Zoe the cat was found lying on a towel with her three newborn kittens, completely soaked through after a night of heavy rain.
Only one of the kittens, Fern, survived the ordeal, an SPCA spokeswoman said.
"A newborn kitten is particularly vulnerable to the elements and unfortunately one of the kittens had already died by the time they were found. One of the kittens was too weak and didn't survive. The last kitten, Fern, was found tucked into Zoe trying to feed despite the terrible cold."
The mother cat's uterus had prolapsed, meaning she was unable to move and help her kittens.
