Cat owners have sent a warning after a spate of deaths they believe to have been caused by antifreeze poisoning.

Three cats from Peel Street died within a week of each other after developing symptoms consistent with those caused by ingesting antifreeze.

Tracy and Chris Brown’s cat Millie was the first to fall ill and sadly had to be put down after four days.

Then Sarah and Paul Frodsham’s cat Hugo, and a neighbouring cat called Peaches, belonging to Tom Parkinson and Anna Anderson, also became ill.

Hugo and Peaches were then both put down on the same day.

All three cats were weak and unsteady on their feet and had acute kidney failure – symptoms associated with being poisoned with anti freeze.

Tom Parkinson said: “Peaches loved being outside and was a lovely character. It’s awful. It’s essential people know about this.”

Fiona Clegg, from Bond Street Vets, and Magda Jaszczak from Wright and Morten vets on Cumberland Street, looked after the cats. They said the severity of the kidney failure indicates antifreeze poisoning.

RSPCA officers are investigating but a spokesman said it’s hard to determine whether the incidents are malicious or accidental due to leaks from containers or cars.

She said: “If a cat ingests even a small amount of poison this can lead to kidney failure and death.

“Deliberately poisoning an animal could mean a £20,000 fine or six months in prison. If you are concerned that your pet may have been poisoned, please contact your vet as soon as possible.

“People should be careful that antifreeze is properly disposed of rather than dumped.”

Police say they found no evidence to prove it was malicious.

Inspector Steve Griffiths of Macclesfield NPU said: “We take all reports of this nature seriously and will thoroughly investigate any reports of possible animal cruelty.

“We would advise all residents to keep an eye on their pets and to contact a vet if they notice any unusual symptoms.”

Signs of poisoning can include lack of appetite, vomiting, breathing difficulties, unsteadiness and seizures.

Cats are attracted to antifreeze due to its sweet taste. There is a campaign at change.org to ban all antifreeze unless it contains a bitterant to deter animals.
