Staff held a contest for visitors to name the baby tigers. Saturday morning they announced the winners along with the names.
The tigers are three months old, the biggest is already 22 pounds. Zookeepers say they love the cooler weather and expect to see more and more of them.
"Tiger cubs of course are a huge pull. I personally walk by them every day that I'm here. So I can imagine it has gotten a lot of people in especially on a nice day like this. It's fun to come out and watch them be active and everything," said Jill Roderick with the Peoria Zoo.
These cubs are four out of only 16 born this year in American zoos.
