The Branhams of Summerville had been thinking about getting another cat.
Jordan, 11, Taylor, 13, and Cade, 7, talked about it with their parents on Wednesday.
On Thursday, they saw a photo of a kitten needing a home accompanying a story in The Post and Courier about the Charleston Animal Society being swamped with homeless animals.
"It was just like an omen," said their mother, Kim Branham.
So, on Friday, the Branhams decided to make room for one more feline to join their household of two cats, a sugar glider and a cockatiel.
"I wanted a cat so bad, so bad," Cade said.
The animal society reported a brisk business in adoptions and people volunteering to foster homeless animals in response to the Thursday story.
"My phone has been blowing up. It's amazing," said Kay Hyman, society spokeswoman.
She said the depth of the public response brought tears to her eyes.
Those opening their home to the animals on Friday included Jim and Karen Baldwin of Goose Creek, who decided to foster three puppies in addition to the three dogs they own and another dog they are fostering.
"What's a couple of weeks for puppies?" Karen Baldwin said.
Their three children volunteer at the society.
Through this weekend, adult cats are free at the shelter. Puppies, kittens and dogs are 20 percent off.
