"Most of the cats don't hunt, especially considering they are currently well-fed," she said.
"There are only 10 of them, and they are no more of a threat to wildlife than the domestic cats in back yards down the road. I would be devastated if I was forced to abandon them."
In addition to caring for the cat colony, Mrs Chapman actively identifies any new dumped stray cats, had them spayed, at her own expense, and found homes for them. The stray cat population was therefore very effectively controlled.
"In addition to asking Betty to behave illegally, this would also be an act of total cruelty, as the cats are currently healthy and well cared-for, and would go from being fed daily, as if they were owned, to being abandoned, Mr Logie added.
"There are actually no grounds for the claims made by Bay Bush Action, or for the decision made by the council. We'd love some support from the people in this community, and beyond, to help us get this decision overturned.
"Betty and her team should be commended on the great work they carry out."
The SPCA is due to meet with council representatives on Monday to present a swathe of information that it says the board did not take into account.
