Mona Patterson is an actress best known for her role in a show from the 1960's called I Married My Mom. She is one of Cat's favorite actresses, and she only appeared once in the series in the episode Car, Rain, & Fire.
In the episode, believing that she had died, Cat takes Tori and Jade on a road trip to her house in San Diego to honor her and leave a candle on her doorstep. However, they find out Mona is still alive, and Cat had been confused by a headline that said "Mona Patterson joins The Dead", a TV show Mona was cast in to play David Schwimmer's wife. Mona did not enjoy seeing Cat, Tori and Jade outside her house, and she wanted them to leave, taking out a soaker and spraying them to get them away from her property. Her house catches on fire when Cat's cinnamon bun scented candle set a fire in the front of her house, and soon after, she was rushed to hospital where she was resting very uncomfortably. When Tori and Cat find out, Cat is shocked, and Tori gestures to Cat to never speak of this to anyone. It is unknown what happens to Mona Patterson next.
