Three trolleys containing close to 20 cats and kittens have been abandoned outside the Rotorua SPCA.
Workers arrived at the shelter this morning to find the trolleys and a single cat-cage covered over containing 10 adult cats and eight kittens, Rotorua SPCA area manager Sue Kinsella said.
The felines were found about 7.45am today, with workers unsure of how long they had been there.
Kinsella said they expected that the abandonment happened early this morning or late last night.
All of the cats were showing signs of cat flu and distress and were being checked over by a vet, she said.
