A cat in a Nebraska animal shelter has made headlines for his skill with a door handle, but hes still waiting for an adopter to open their door to him.

Staff started to go crazy knowing they shut certain doors when they left at night but those same doors would be open in the morning......then today we discovered this, the Capital Humane Society in Lincoln wrote July 27 on Facebook .

The post included a video of a black cat named Grimsen leaping up and grabbing a doors lever handle with his paws, managing to pull it down to let himself out.

Grimsen is the ultimate trickster, the shelter wrote.

The cats adoption listing also cites his ingenuity, calling Grimsen a VERY smart guy who has managed to teach himself how to open lever style doorknobs and walk freely amongst the other shelter cats strutting his stuff.

Early in the morning on the day of the Facebook post, the shelter staff noticed that three different doors were open and Grimsen was strolling the hallway. He was returned to the room he shares with two other cats, but around noon, Grimsen was spotted walking down the hallway again, veterinary and behavior assistant Hillary Brandt told HuffPost in a Facebook message.

Not long after, Grimsen was once again returned to his room. This time, he was caught red-pawed opening the door.
