Catherine Young, 54, smeared 12-week-old Morritz’s face with his own faeces before putting him in the washing machine at her home in Clacton, Essex. Colchester Magistrates’ Court heard the black and white kitten died after being put on a full cycle.
Young admitted to two animal welfare offences following a prosecution by the RSPCA.
She has now been disqualified indefinitely from keeping all animals.
The court heard how the RSPCA was contacted after Young rang a veterinary practice on June 15 to say one of her kittens had died at home.
She arrived at the practice that evening with Morritz – who was cold and stiff with wet fur – and one live kitten called Bobbitz.
When questioned about what had happened by a vet, Young admitted she had put Morritz in the washing machine because she had been “naughty” and pooed in the house.
She said she had rubbed the kitten’s face in the faeces to tell her off before putting her in the washing machine on a short cycle to clean her fur.
She said she had done this before and Morritz had been “fine”.
Young also admitted to the vet that she had previously withheld food and water from both kittens for at least 24 hours as a punishment.

She said: “No other animals were seen at the address, however empty litter trays, cat litter, a broken cat carrier and a bag of cat food were still in the kitchen.”
In his witness statement to the court, the vet said: “It is my opinion that the deceased kitten had undergone significant unnecessary suffering by being deliberately placed in a washing machine and then this being placed on a wash cycle.
“The spinning of the machine and the water would have caused significant pain, injury and huge amounts of stress.”
Young, who represented herself, said she had a personality disorder and mental health issues.
She was also fined £200 and ordered to pay £145 in costs and a £34 victim surcharge.
Bobbitz has been renamed Gulliver and is doing well in a new home.
