The kittens, who were found toward the end of June, were estimated to be between 1 and 2 days old at the time. Their eyes were still closed and they had their umbilical cords attached.
They had been left in a dumpster filled with tar and wood pellets. Sarah Varanini, foster care coordinator at the Sacramento SPCA (SSPCA) in California, told The Dodo it's likely a stray mother cat thought the dumpster was a safe place to keep her babies - although she didn't rule out the possibility that the kittens could have been purposefully thrown away.
The newborns were taken to the SSPCA and placed into foster care with two staffers, who had the bottle-feeding experience needed to help the young kittens grow big and strong.
