The feral cats at Lehigh Valley International Airport will trapped, not euthanized, which was the original plan.
The cats will be trapped, spayed or neutered and then sent to a farm in Bath.
Animal lovers were upset last month when the airport said it would consider killing the cats.
"I consider it to be a win-win," Martha Kahan, president of No Nonsense Neutering told the paper.
Over the weekend, she started trapping the cats. There are about 20 on airport property.
They airport is picking up the cost -- $35 per cat -- for spaying and neutering.
