Tallulah Strickler is a Principal Strickler's cat and a main villain of the show. She is one of the very few people that know Spot can talk and is Scott Leadready II.
When Strickler is around, she acts all sweet and playful, but when it comes to Scott, Leonard, and Pretty Boy she's evil and hyper. The most notable episodes that revolve around her talking are Pet Project, Tallulahpalooza, and Saving Mr. Jolly. She also knows that Scott is a dog and always tries to get people to notice as well. She often hides her evil personality from Strickler.
