The shocking incident happened at some time on Tuesday afternoon in Kells.
Tigger, an eight-month-old ginger tom, had to be put to sleep by a vet as the bolt had punctured his heart.
The much-loved pet was owned by Heather and Trevor Davidson.
Their son Michael appealed for anyone who had any information or who might have witnessed this terrible act of cruelty to contact police. My father recently suffered a stroke which impacted on his sight, so we got the cat to help him in his recovery, Michael said. He has been going through a really rough time and Tigger brought him a bit of joy.

Two Proud Boys accused of leading a mob to Congress followed a bloody path to get there. Law enforcement did little to stop them. A protester was burning an American flag outside the 2016 Republican convention in Cleveland when Joseph Biggs rushed to attack. Jumping a police line, he ripped the man s shirt off and started pounding, he boasted that night in an online video.
But police charged the flag burner with assaulting Biggs. The city later paid US$225,000 to settle accusations that police had falsified their reports out of sympathy with Biggs, who went on to become a leader of the far-right Proud Boys.
Detectives are continuing to seek information on the whereabouts of a wanted man, after he was jailed in his absence for attempting to buy grenades over a secret area of the internet.
