Nelson

Nelson is a small ginger cat who, like Carson, has the ability to speak English.

Early Life
Unknown.

Meeting The Elegant Trio
When Edwin and Charles thought their cat Carson was lonely, they brought him a friend, who was Nelson. They originally didn't trust him because they found a notebook with plans to kill Edwin and Charles and take over the apartment, which appeared when he arrived. It turned out it was the peasant Coffy Leland's notebook. When Coffy threatened Edwin and Charles with a pistol, he bit Coffy's hand, which scared the peasant away thinking he had given him rabies.

When Coffy and The Tramp Squad conquered the apartment and locked Edwin and Charles in their cell, Nelson freed them and helped them call the police.

One day, Nelson returned to the apartment, asking to officially live in the apartment. Charles accepted immediately, but Edwin was having doubts because he thought that he would replace Carson (who thought the same as Edwin). They accepted, on the condition that Carson be his mentor and teacher.
