A "savage" Sydney northern beaches woman who stabbed her therapy cat 20 times and threw its lifeless body from a window has been sentenced to two years in jail.
A court heard on Wednesday that Celina Paige Shead told a psychologist she wanted to "squish the life" out of the cat because it was cute.
Documents tendered to the court showed that the 20-year-old smirked while being questioned by NSW Police after the October 2019 incident.
Magistrate Mark Richardson sentenced Shead to two years in jail, with a non-parole period of 15 months, after she pleaded guilty to two charges including torturing, beating and causing the death of an animal.
Shead admitted stabbing the 11-year-old cat, named Ginger, 20 times on the morning of October 23 before throwing it from the second-floor bedroom window of the Dee Why flat she shared with her family.
Police prosecutor Adrian Walsh told the court that Shead had failed to show remorse and told a psychologist: "You know when something is so cute you want to squish the life out of it."
"This isn't an incident of cruelty by way of neglect," Sergeant Walsh said.
"This was a small vulnerable animal subjected to deliberate cruelty. It was an abhorrent act of cruelty."
When she was interviewed by NSW Police, Shead had denied owning a cat or knowing anything about the dead animal found in the garden bed.
Sgt Walsh said she was "sinister, smirking, almost laughing" during the interview.
Officers found a knife with white hair stuck to it on a kitchen bench in the flat, spots of blood on a rug and adoption papers.
"The entire time police were speaking to her she had a smirk on her face," the police fact sheet states.
A second cat was retrieved from the unit and placed in the care of the RSPCA.
The court heard Shead had been diagnosed with borderline personality disorder and Mr Richardson said her chances of rehabilitation were "fair" - despite doctors not being able to identify any underlying problems.
But the magistrate described her crime as "savage in its cruelty" before sentencing her.
"On the face of it, it's difficult to imagine a more cruel act than this," Mr Richardson said.
Police were called after neighbours heard Shead yelling at the cat the night prior and an animal in distress on the morning of October 23.
Neighbours discovered the cat lying dead in the apartment block's courtyard with two boxes of kitty litter, which Shead had also dumped out the window, lying on and around the body.
Her father told police that Shead had failed to bond with the animal after adopting it as a therapy cat from the RSPCA the previous week.
Shead was placed in custody in October 2019 having been put on an intensive corrections order for unrelated charges just days before the animal offences.
With time served she'll be eligible for release in January 2021.
Shead was also sentenced to three months prison after pleading guilty to stealing a dog from outside a shopping centre in September 2019
The white pomeranian, named Bella, was dyed orange when it was recovered by police
She also received a lifetime ban from owning an animal.
