A spokesman from Worthing Cat Welfare Trust, in Orchard Avenue, said: “It has been brought to our attention that a much-loved cat has been found murdered and mutilated in the Goring area.
“We send our sincere condolences to his family.
“We would ask cat owners in and around Worthing to keep vigilant and please keep your cats in at night.
“How someone could do that to a defenceless cat just beggars belief, this person needs help, please report them to the police and let’s stop this before another cat dies, and another family has to grieve.”
Sussex Police has been contacted for a comment.
