The pet could be seen landing on a tarmac drive before limping away

The 16 and 17-year-old, who cannot be named for legal reasons, had earlier admitted animal cruelty.

A 14-year-old, who filmed the ordeal in Druids Heath, has admitted aiding and abetting the cruelty. The case on all three was adjourned until 1 August.

Christopher Lees, 18, of Wilsford Close, Druids Heath, has admitted cruelty and may be jailed on 14 July.

The 16 and 17-year-old were arrested last year after the footage, filmed on a camera phone, was sent to other children, Birmingham Youth Court heard on Tuesday.

Magistrates ordered pre-sentence reports on the pair and the 14-year-old. Mr Lees has been warned that he could face imprisonment when he is sentenced in an adult court on 14 July.

The cat, called Kharlo, owned by a local student, was put down by a vet after suffering brain damage and multiple fractures during the ordeal last October.

Nick Sutton, prosecuting for the RSPCA, said: "The most disturbing feature is not only the sustained cruelty, but also that that was seen as entertainment - it was being done for no other reason than entertainment.

"These people were enjoying it and sending it around on phones."
