Elmo is Paige's pet cat that Pat has adopted as his son.
Elmo is a eleven year old half Maine Coon cat, found in a dumpster and taken to Tree House Animal Shelter in Chicago, where he was barely even washed up when Paige adopted him. He was brought to Pat's apartment on October 4th, 2016. Elmo has Cerebellar Hypoplasia, causing problems with his back legs, anxiety, which causes him to chew off patches of his fur, and OCD. Whenever Elmo does something weird or dumb, Pat and Paige insist that "He's doing his best!".

- “Oh, what a good boy. He's done nothing, but he's a good boy. You know why? Cause he's the best child ever. I sometimes think about people with real children, like, human children, and wonder if they can feel even a smidgen of the love we feel for Elmo. And the answer is no. They could never.”

- Elmo's favorite food is his own fur.
- According to Pat, Elmo hates the Chinese.

- Elmo's hobbies include stepping on the keyboard during Twitch streams and licking his own bag.
- Elmo will not eat treats or food given to him, only specialist cat food from his bowl. He will also eat his own fur, and chocolate, despite both of these things being bad for him. During the RE4 Twitch stream, Elmo licked a chocolate cake and Paige had to rush him to the vet. Elmo is big and strong, however, and was unharmed.
