Hamster Spends Final Days Checking Off Bucket List The little hamster is out and about taking selfies in Chicago.

 -- Meet Robin Williams, a sweet and silly Syrian hamster from Chicago.

Unfortunately, a veterinarian discovered a "very large tumor" in Robin's abdomen last week, according to his "parents" Arden L. and Riley K., a twenty-something couple from the Windy City.

Arden and Riley are helping Robin live his final days to the fullest with a bucket list of fun adventures.

"Deciding to do a bucket list was easy," the couple told ABC News in an email today. "He already goes everywhere with us, so why not bring him to some of our favorite places around Chicago?"

Although "some people don't consider hamsters a 'real pet,'" the couple said, Robin "is just as important and special as a dog." They added that Robin is "the sweetest creature" who "loves snuggling," giving kisses and falling asleep in sweatshirt pockets.

Robin, who's turning 2 in April, has already checked off a few things on his bucket list, Arden and Riley said.

The little hamster has taken a selfie outside the Art Institute of Chicago, watched the sunset go down on the Chicago River and has even gone out for some deep dish pizza.

Today, Arden and Riley said they will be taking Robin to the outdoor public sculpture "The Bean" (formally known as Cloud Gate) to snap a picture and get some ice cream.

In addition to outdoor adventures, the hamster has also been doing a lot of fun things at home with his two bunny "siblings," Poppy and Pippin.

Robin has gotten to "be famous for a day" in a little mini red carpet event with the bunnies and has also built an epic blanket fort and watched movies all day with his family, Arden and Riley said.

"As a small pet mom my favorite quote is, 'Sometimes the smallest things take up the most room in your heart,'" Arden said. "And that can't be truer for us."
