A 38-year-old woman has been fined £170 for throwing a kitten at her neighbour's front door.
April Hawes was caught on CCTV flinging eight-month-old Shadow twice at the property inhabited by the cat's owners, after becoming annoyed that their pet kept coming into her garden.
The woman can be heard shouting "I'm going to knock her out" whilst crossing the road with Shadow.
The animal landed on the pavement and suffered soft tissue damage, and is now reportedly "very nervous".
Hawes entered a guilty plea to causing suffering to a protected animal, and appearing at King's Lynn magistrates in Norfolk, admitted picking up the cat and throwing it.
The court was told Hawes had said she did not wish to cause harm and was remorseful, with Anne-Marie Sheridan, defending Hawes, claiming she suffered post-traumatic stress disorder (PTSD).
Magistrates sentenced Hawes to a 12-month community order with 30 days' rehabilitation activity.
She was also ordered to pay £85 in costs and a victim surcharge of £85.
Owners Kevin Yarham, 33, and his partner Sophie Baker, 26, said the sentence was "a disgrace and far too soft".
"She picked the cat up by the scruff of the neck and threw him violently twice," Mr Yarham said.
"The sentence given was a disgrace not just for us but for all cat owners an animal lovers."
He continued: "People who PTSD would be disgusted she has given this as a excuse for her action an using this mental illness as a get out of jail free card."
