Pidsley is the secondary minor antagonist in Series 1 and a secondary major antagonist in Series 2. He is the farmer's cat who desires to be the sole recipient of his attention. He's jealous of Bitzer's relationship with the farmer and he ever hates the flock, thinking of them as stupid and beneath him.
Pidsley is often trying to get rid of the Flock, and has notably threatened them or used them in various schemes. He tries to use evidence against them, but is often outsmarted, and has been seen to get himself in trouble for trying to stop them. He very much hates them, though it is unknown why. This cat try's to kill a poor little mouse who is friends with the Flock.
- While appearing as an antagonist in Series 2, they are not so much in Series 1, as in the episode Saturday Night Shaun, Pidsley is invited to the flock's barn and hangs out with the Ducks.
- He nevered appeared in other seasons after the We Wish Ewe A Merry Christmas which was the final episode of Season 2. This was probably because The Farmer gave him to his niece for Christmas.
