The owner and staff at Divas Den, and workers at a nearby business have been feeding the cats for many months but with another blossoming cat expecting a new litter, say the situation cannot continue.
"They are only going to keep on multiplying," worried shop owner Melinda Flingsby says.
"If we get any more we are going to be the crazy cat ladies."
She and co-worker Leanne Jones do not want the cats harmed.
Mackay Regional Council manager of health and regulatory services, Craig Shepherd, said council had not experienced an increase in reported feral cat sightings.
However, over 100 cats this year have been re-homed from the council pound.
Mr Shepherd said residents should contact council if they are experiencing an issue with stray or feral cats on their property.
He said that as a last resort the council does provide cat traps for hire.
"Any cat caught should be brought to the Mackay Pound where it will be checked and scanned for identification," he said.
For information or to register your pet contact the council on 1300 MACKAY (622 529) or visit www.mackay.qld.gov.au.
