Dianne is the owner of Nellie's Bazaar in The Warehouse Complex, George St.
The volunteer-run op-shop helps fund TA Care and subsidises the cost of raising animals so that people can adopt them at a "reasonable cost" - around $100.
No cats are housed at Nellie's Bazaar, but they are often sold from there.
Taking on unwanted kittens - and sometimes the mother cat - is no easy or cheap task.
"If we take on a mother cat and her newborn kittens then we'll need to look after them for eight weeks before they can be adopted."
The cost of health checks, worming, medication and defleaing a kitten is about $300.
"It's not cost effective for us to continue like this," Dianne says.
"We're not making any money - we're simply providing a service to the community."
Dianne has a dream to raise enough money to rent or lease a property in Te Awamutu to be used as a cattery.
"This would mean that the community and volunteers could be involved in raising and caring for the animals."
