A woman beheaded her two pet snakes with a pair of scissors after downing seven cans of lager in an alcohol binge.
Police discovered Jennifer Lampe, 28, with the severed heads of her dead pets and with the body of a boa constrictor moving around her neck.
Telford Magistrates' Court in Shropshire heard Lampe killed her two metre boa constrictor and her bull python after feeling "unwelcome" at her sister's house.
RSPCA prosecutor Roger Price told the court Lampe had consumed seven cans of lager and shots of amaretto and whisky at the house in Church Stretton, Shropshire.
Mr Price told magistrates: "I strongly suspect you are going to want (pre-sentence) reports.
"This is a case where two snakes owned by the defendant were killed by her and you will hear evidence that these snakes have suffered in the process."
The court heard Lampe had lived with her sister since May last year and killed the snakes because she feared she was no longer welcome to live at her address.
Mr Price added that the defendant's dislike of her sister's boyfriend had caused friction between them, which "came to a head" on April 8.
"She became very hysterical about the situation," Mr Price told the court. "She went into the kitchen and took scissors out of the kitchen drawer, and a knife, and retreated to her bedroom, where she kept the two snakes."
Lampe's sister, who was not named in court, then went to see her sibling, saw blood, and took the view that she and her boyfriend should leave the property.
Mr Price continued: "The police then arrived and found the defendant with the boa constrictor around her neck. It was still moving but it was missing its head.
"The bull python had also been decapitated and was still in her bedroom."
During a police interview, Lampe said she thought she had "got to the point where she was going to be asked to leave" her sister's address.
Lampe, of Market Drayton, pleaded guilty to causing unnecessary suffering to the snakes "by doing an act, namely cutting their heads off" contrary to the 2006 Animal Welfare Act.
She was granted unconditional bail to return for sentence on August 18.
