Nemo

Nemo is Francine Frensky's pet cat.

History
Oliver Frensky found him in an Elwood City Dump landfill in which he worked which led to the adoption of Nemo. Initially, Catherine had adopted him as her own pet, naming him Rose Petal, but later, she realized that he was more suitable as Francine's pet, leading him to be renamed Nemo.

Like Pal, in some episodes he is shown to be able to communicate with other pets, human babies, and toys. He is usually cast as an antagonist in these situations. During these interactions, especially with Pal, he is prone to insults and sarcasm, but can occasionally be helpful.

Trivia
