Jason Metcalfe aged 29 year old is believed to have flew into a drunken rage when female tabby Bonnie approached him in the street in Earby, Lancashire.
His attack was witnessed by a nine-year-old who was playing nearby.
Metcalfe, of Kenilworth Drive, could not remember anything of the incident on September 28 last year when he was interviewed by the RSPCA the following day.
Chris Wyatt, prosecuting, said the cat suffered various injuries to its head and face and died from the severe head injuries, he said:
"Whether he was drunk or not he was clearly in a rage and took his frustrations out on the cat. It is not a humane way to deal with an animal,"
Metcalfe pleaded guilty to failing to meet the needs of the cat by not protecting her from the pain she suffered before death.
