Entering as the first-ever duo on The Masked Singer is Cat & Mouse and they survived to remain another week on the show. This means that judges Davina McCall, Rita Ora, Jonathan Ross and Mo Gilligan and viewers at home are puzzling over the duo's identity.
During the show the different characters give clues to help fans figure out who they might be. The judges also have a go at guessing who it is at the end of the performances.
Cat & Mouse went up against Phoenix in the first episode and here are all the clues to their identity.

Cat & Mouse clues
During their clue section there were a lot of hints suggesting Cat was a detective. The number 20 million came up and Cat said they were used to dealing with legalities.
For Mouse they were seen with different spices and their riddle was: "I'm on the case, I'm not afraid, you stole the cheese, and some jade."
Jonathan said Geri Halliwell for Mouse due to the spices but did not have a guess for Cat. Davina did not think the duo were a couple and suggested Susanna Reid and Ben Shephard from GMB, Mo said David Walliams and Matt Lucas and Rita thought McFly frontman Tom Fletcher and his wife I'm A Celebrity...Get Me Out Of Here! winner Giovanna Fletcher.
Some fans agreed with Jonathan about Geri Halliwell, others believe Emma Bunton could be one half of the duo and Tom Fletcher was also suggested but paired with his sister Carrie Hope Fletcher.
