"If the kittens hadn't been meowing she wouldn't have realised they were there."
The kittens were 4 weeks old and are being cared for at a foster home. Also last week two kittens were found inside a box outside the door of a house.
They were 8 weeks old.
"We've also had quite a few incidents lately where people have moved out and have left their animals, both cats and dogs, behind," she said.
"Hate to think of boxes of kittens being left to fend for themselves and they could be run over, starved to death and, if they survive, increases your feral population if no one catches them."
Ms Honeybun said the key is for people to desex their animals.
The 4 and 5-week-old kittens needed to be with their mothers until they were 8 weeks old, she said.
The breeding season for kittens usually ran from November through to March and April.
"If they need advice for their animals, please give us a ring and we'll be more than happy to help and provide the advice."
Abandoning animals without making provision for their care is an offence under the Animal Welfare Act 1999, punishable by one year in jail and/or a $50,000 fine.
