A "loathsome" man who cooked a friend's cat to death in a microwave has been jailed for six months.
Paul Henry, 45, from Gainsborough, then boasted about what he had done to his then girlfriend in a text message that read: "Claire, just cooking Andy's cat. En route."
The cat's owner Andrew Parsons, 38, had left friends Henry and Phillip Mathers at his apartment, also in Gainsborough, at 4.30pm on July 26, last year.
On his return from work four hours later Mr Parsons found his beloved black and white cat, Suzie, dead in his microwave.
Significant damage had been caused to the property, including the smashing of Mr Parsons' television, with the words "Menu. Fried cat. £1.20" written on the kitchen wall.
District Judge John Stobart described Henry's actions as "brutal", "sadistic" and "the worst case of animal cruelty".
Lincoln Magistrates' Court heard how Henry attempted to pin the crime on Mr Mathers.
While Mr Mathers admitted taking liquidised amphetamine in the bathroom and stealing Mr Parsons' electric razor, he claimed to have left the property before the cat was cooked. He was charged with cruelty to an animal and criminal damage but was later acquitted.
Passing sentence, Judge Stobart said: "Mr Henry actively pursued to shift the blame of this appalling act on to Mr Mathers who, I'm sure won't mind me saying, is not the sharpest knife in the drawer.
"There is no credible evidence which places Mr Mathers in the flat at the time of this despicable act. However, the evidence that Mr Henry was there is overwhelming.
"He has shown a lack of consistency throughout this process and what is of crucial importance are the text messages he sent to his then girlfriend."
Passing the maximum sentence law would allow, Judge Stobart added: "I can't think of a worse case of animal cruelty. You have acted in a manner that is loathsome."
Within an hour of Mr Parsons leaving his flat to undertake a gardening job, Henry had sent two texts to his then girlfriend which suggested the ordeal was already under way.
Giving evidence during the trial, an emotional Mr Parsons explained: "I noticed my light fitting had been pulled down and that there was glass on the floor. I then walked into the kitchen and found my cat's remains in the microwave. I was sickened and distraught."
Mr Henry also received a life-long ban on keeping animals.
