Spartacat is an anthropomorphic lion and the official mascot of the Ottawa Senators. He is also known to be quite an acrobat as he has been seen swinging through the Canadian Tire Centre arena to get the crowd pumped up before games. An immediately recognizable part of Ottawan society, Spartacat does his part as an active member of the community by visiting hospitals, schools, and children's hockey games. He has been involved in the "Read to Succeed" literacy drive that has been initiated by the Ottawa Senators to educate children on the importance of reading and participates by visiting schools in the Ottawa area to draw the attention of children to the literacy message.
Spartacat has a fierce rivalry with Carlton the Bear, the official mascot of the NHL ice-hockey team, the Toronto Maple Leafs.
