The Bidens have welcomed a new family cat to the White House.

Willow, a 2-year-old gray tabby, is named after the first lady's hometown of Willow Grove, Pennsylvania. She joins Commander, a German shepherd puppy that has been at the White House since December.

Ever since George Washington took office with horses and hounds in tow, presidents have welcomed animals into their lives.

Thomas Jefferson kept a mockingbird and a couple of bear cubs during his presidency. Theodore Roosevelt, famous for his love of the great outdoors, had parrots, ponies, bears, snakes, lizards, a zebra and a one-legged chicken. Calvin Coolidge counted a raccoon among his many animals. Woodrow Wilson had sheep that helped keep the grass trimmed during World War I.

But most modern-day presidents have stuck to more traditional pets: cats and dogs. And throughout the years, these pets have become celebrities of sorts.

President Theodore Roosevelt's eldest son, Teddy Jr., holds a macaw named Eli circa 1902. The Roosevelts had all kind of animals, including lizards, snakes and a one-legged chicken.
