She found her dog Darla emaciated in the middle of "no man's land" and her son Jake found their cat Onyx with an infected injury and on the brink of death.
"I had no intention of opening up a rescue centre as this was just a hobby of mine, but after people knew who I was and what I did for the animals they started to come in quick and I can't say no to a helpless animal."
Most of the neglected animals were kittens and pups.
She has started a campaign called Last Chance ResQ and is looking for sponsors and food donors to help with animal care.
"It is so rewarding to see these cats who were full of worms and sick with cat flu afraid for their life struggling to survive to be buzzing around the house purring and playing, Ms Duke said.
"I have a fairly clear vision for the rescue and that is to open up a rescue/orphanage centre where volunteers can come and sleep the night to mind the cats and dogs and training and rehabilitation would be on site. I feel the situation is only going to get worse before it gets better and ultimately I would love to spread awareness that a cat and dog are forever not just a christmas present."
