Devastated owners have issued a warning after three cats were reportedly killed by the same dogs in one night.
The horrific incidents in Kennington have left residents fearing that more moggies may be at risk in the area, but police say no criminal offences have taken place.
Mardol Road resident Maxine Goldsmith said that she was woken up early in the morning on Friday to "quite a bit of commotion".
Shortly afterwards, her neighbour knocked on her door to break the news that her family's beloved cat, Dana, had been attacked.
She said: "There were several men laughing and joking, and a lot of barking and squealing.
"At around 1.30am my neighbour knocked on my door to tell me to prepare myself that Dana had been attacked.
"Unfortunately, by the time I had got to him Dana was already dead."
Mrs Goldsmith said that her neighbour, who tried to intervene in the attack, described the first dog as a red pitbull with no lead, with two other dogs also present.
She added: "There was about three men on push bikes with two lurchers also off the lead shouting 'Where's the red pitbull where’s the red pitbull', they said 'sorry about that dog got out the unlocked gate' and said they’d be back in a minute but they never returned."
Police were called to do a search of the area, but found nothing.
Tragically, a further two cats would later be found dead in a similar manner, in Guernsey Way and Magazine Road.
A witness to the Guernsey Way attack, who asked to remain nameless, said that the men fled on their bicycles when they heard that police were attending.
"I hope getting this out there will mean others don't have to suffer losing their pets in this way"
She said: "I can't give much more information other than the dogs have ripped apart the cats, while the owners have looked upon it and done nothing to stop it.
"I hope getting this out there will mean others don't have to suffer losing their pets in this way."
A police spokesman said: "Police were called at 1.30am on Friday and it was reported that two dogs had bitten a cat in Mardol Road, Ashford.
"Officers attended and carried out a search of the area, but the dogs were not located.
"Later that day, a similar incident was reported to have taken place in Guernsey Way, Ashford, at around the same time as the first incident.
"No criminal offences are believed to have taken place."
