Take a look at these new images of the baby tiger cubs at the Toledo Zoo.

The cubs were born last month to first time mother Marta. They turned one month old Wednesday.

It will be several months before visitors will be able to see them.

The cubs are the second generation of Amur Tigers born at the zoo.

Once known as Siberian Tigers, they are critically endangered.

Take a look at the Zoo's Facebook page to see more images of all the other animals.
