Three animals including a black cat have been discovered dead on the streets of Medway.
Horrified volunteers from Animals Lost and Found Kent have been called out to deal with the incidents.
In the village of Wigmore near Rainham owners found their black cat dead from injuries involving a sharp object last Wednesday.
Another cat was found mutilated in Gillingham last Monday. It, too, had been slashed with a sharp object.
And in April volunteers were notified that a kitten had been decapitated near the Medway Maritime Hospital. It later turned out to be a mutilated fox cub.
Police are investigating the incidents and are understood to have added them to their Operation Takahe database, started in the wake of the 2015 Croydon cat killings.
One person is thought to be responsible for the deaths of more than 400 animals in Kent, Surrey, south London and Buckinghamshire.
A total of 10 cats were killed between December 21 and December 31 last.
Animal rescue group the SNARL is helping co-ordinate efforts to find the killer. A spokesman said: “Someone, somewhere knows who this individual is. Shop them and do it now.”
