Criminal investigators in Russia are probing an horrific video in which a student hurls a kitten into a scorching hot oven.
The torture came during a teenage party in Krasnoyarsk, a city in Siberia.
The black cat is thrown in the 375C oven by a man who has been identified as 18-year-old Kirill Beryozin as he and others laugh and joke, say police.
The sick abuse was filmed by an unknown male friend and posted on Beryozin's social media.
During the clip, the first voice - belonging to the person filming, is hearing saying: '375 degrees! Wh***!'
A second voice replies: 'Let's do it one more time!'
A third asks: 'What will happen to it?'
The first person says: 'I'm in hysterics. Shame, cat is not visible there!'
The third then says: 'Drag him out, whore! He f****** did not understand!'
'Look, cruel attitude to animals!' the second person says before the cat is hurled into the oven.
Over laughter, the first person says: 'Oh, that was tough! 375 degrees! You've broken his spine!'
The kitten's condition after the torture is unclear.
Later one of Beryozin's accounts was closed, the other deleted.
The student later changed his online family name to Kalashnikov, but then deleted this account, too.
Beryozin had been previously pictured online with his cat.
A spokesman for the Russian Investigative Committee, which probes serious crimes, said: 'A video was posted on the internet where teenagers inKrasnoyarsk region are torturing a cat during a house party.
'They put it into a hot oven. At the moment the circumstances of this incident are being investigated.
'A decision will be made based on the results of these checks.'
Beryozin is a student attending the prestigious Krasnoyarsk College of Radio Electronics and Information Technology.
The video sparked a furious backlash on social media.
'These young people are absolutely mad, as if they are not human…,' said one shocked viewer.
'He is obviously enjoying it, he gets excited when he is hurting the cat,' complained another. 'Tricks with a human being will be the next in his chain of entertainments…'
A woman asked: 'Is it a new trend among young people to torture animals?
'Almost every day I come across a new case.'
Russia recently increased the jail terms for cruelty to animals. Individuals can be jailed for up to three years.
If torture is inflicted by a group, the penalty is up to five years.
