Fake medicine almost killed my cat - here's how to keep your pet safe

When Alan gave his Persian tabby cat, Smokey, its regular flea treatment last year, he thought nothing could go wrong.

The 45-year-old from Preston had used the same brand - Frontline Plus - for years without any trouble. But within hours of applying a new dose he'd bought online, his usually lively tabby was violently ill, vomiting and refusing food or water.

"I bought it from a major online site and the price seemed similar so I didn't suspect anything at the time," Alan told the BBC's Morning Live.

Alan's story comes after the government recently issued an urgent warning about fake veterinary products being sold online.

With vet bills up 60% in the last decade, more owners are turning to the internet to hunt for bargains.

The vet that Alan took Smokey to initially found nothing abnormal, but when his condition deteriorated, scans revealed a blockage in his intestines. Emergency surgery saved his life - at a cost of £3,000 - and tests later confirmed he had suffered a toxic reaction.

Alan returned to the vet with the packaging. At first glance, it looked genuine, labelled as "Gatti" - which Alan assumed might be an Italian version of the medication.

But when the manufacturer was contacted, they confirmed it was counterfeit and laboratory testing found it contained a chemical highly toxic to cats.

"We felt really guilty about the fact we had done this to him," Alan said. "But finding out it was fake medication, we were really angry.

"It's horrific and I had absolutely no idea there was such a thing as fake pet medication."

Helen Barnham works at the Intellectual Property Office (IPO), a government team tasked with trying to stop the sale of counterfeit goods.

The team has issued more than 100 seizure notices for the selling of unauthorised animal medicines and supplements, preventing around 18,000 illegal items from reaching consumers.

"Criminals copy these products to make them look like the original and it's all to make money, they don't care about the damage or harm," she explained.

According to the IPO, the online seller who Alan bought the medication from managed to sell 211 batches of suspected counterfeit pet medications and supplements.

"If it's not from a vet or a trusted seller then please be vigilant," Barnham said.

Barnham is urging pet owners to check all pet medicines carefully before using them.

Even if a product looks authentic, there are often subtle clues something is wrong.

• Poor quality, damaged or flimsy packaging
• Spelling or grammar errors on the label
• Missing instruction leaflets or expiry dates
• Instructions not provided in English
• Suspicious smell, colour or texture
• Tablets or pipettes that look homemade or poorly made
• Unusually low prices or deals that seem too good to be true
• Product names that are slightly misspelled or altered from the original brand

Nina Downing, Vet Nurse from PDSA, a vet charity, says she always recommends only giving your pet medicine which has been prescribed by a vet.

"When fulfilling a prescription online, source them from reputable companies that are on the Register of online retailers, brought to you by the Veterinary Medicines Directorate."

If the medication has any of the above warning signs, you should stop using the product immediately and contact your vet for medical advice.

You should also report it to your local trading standards office and notify the brand manufacturer, who may be able to verify if it's genuine.
