A family in Staffordshire is warning pet owners in their area to be aware after their sixth cat died from suspected anti-freeze poisoning in five years.
Peter Jenkins, from Burntwood, says the latest incident saw his one-year-old cat, Button, come back home looking lethargic.
He was taken to the vets where he couldn't be saved, and was put down.
Peter and his wife Tami's first pet cat to die of suspected antifreeze poisoning was Tommy, who died on November 24, 2014 aged nine.
This was followed by Fudge who died on December 29, 2014 aged 14, then Alfie who died on August 7, 2015 aged 11.
Ava died on 3 July 2016, and her twin sister Maxi died a few weeks later, both aged just 11 months. Button died on 17 November.
The couple both still own cats, as well as a number of other animals - many of which they have rescued. And the RSPCA is backing their appeal to warn others what appears to be happening.
The RSPCA is backing the warning, and has provided advice to pet owners.
The charity says signs of poisoning can be seen anything from 30 minutes after ingestion to two or three days.
This can include some, or all of the following symptoms: vomiting, seeming depressed or sleepy, appearing drunk or uncoordinated, seizures and difficulty breathing.
It is also a criminal offence under the Protection of Animals Act 1911 and the Animal Welfare Act 2006 to administer poison, dangerous drugs or substances to an animal; and under the Animal Welfare Act 2006 it is a criminal offence to allow a cat to suffer unnecessarily.
