Precious is Logan's pet cat. She has made a few appearances in Logan's videos. Four of her most notable appearances was in Bowser Junior's Bad Luck!, where she spoke, Bowser's Chinese Food, where she was cooked up as Chinese food, Bowser's Cookies, where she ran across the kitchen, and Bowser Junior's Candy Bar!, where she was in Junior's room. She also makes cameos in every video since the beginning. She is 17 years old, and now has a difficult time taking care of herself. Precious is the only one of Logan's cats from his videos in the past that is still alive.
For Logan's 5th birthday in 1999, his step dad Brian gave him an iguana. However, his mother did not think Logan was taking care of him, plus she thought he was dangerous and had diseases, so she let Logan trade it for a new pet. In the Spring of 2000, Logan got a baby kitten from the trade. She was named Precious by Brian, after a Lord of the Rings character. At first Logan did not like Precious, but he got used to her and had fun, and she became Logan's favorite cat. When SuperMarioLogan began, she would appear in lots of videos. When Logan moved out of his childhood home in 2015, he got to take Precious to the apartment. Now she is still alive, however she is very obese, but seems to be doing extremely well for her elderly age.
