Gobbolino, The Witch's Cat is a children's novel by Ursula Moray Williams, published by George G. Harrap in 1942 with illustrations by the writer.
This sets him apart from other witch's cats like his twin sister Sootica, who have pure black fur and green eyes.
Finally accepting his magic, Gobbolino becomes the pedlar-woman's assistant, but his good heart and unwillingness to cause pain mean he fails at every task he is set.
The witch puts a spell on him, removing his magical powers, and he finds his way back to the farm where he began his journey, his coat having faded to an unrecognisable tabby.
