The Atlanta Journal-Constitution reports that all of the kittens are believed to be rabid.
Vince Farah, a spokesman for the Henry County Animal Care and Control Department, says it's imperative that anyone who came in contact with the kittens come forward because they could have been scratched or bitten. The kittens were given away in late August.
Farah said the odds are 99 percent that every one of the kittens in the litter had rabies.
He said Walmart is helping locate the kitten handlers.
Rabies is a deadly virus if gone untreated.
