A pregnant mother of two in east Hertfordshire reported that her pets were poisoned by an unknown toxin, resulting in the death of one cat and critical illness in others. The incident has led to the arrest of a 32-year-old woman.

Courtney, the mother, stated that her medical alert dog and seven cats became ill after being exposed to what she was informed was opioid poisoning, suspected to be a substance made up of heroin and another ingredient, possibly sprayed around her home. She also experienced temporary blindness after falling ill herself, a symptom associated with opioid exposure. Her two young children were taken to the hospital as a precaution due to developing symptoms such as headaches and upset stomachs, but have since returned home.

The ordeal began when Courtney noticed one of her cats was unable to move on Monday evening. By the following morning, five of her eight cats were seriously ill and seizing. Her service dog, Pickles, also fell critically ill after a brief exposure in the garden but was revived by veterinary staff and is now recovering. However, one cat named Bean died from the poisoning.

Courtney has incurred significant veterinary bills, initially estimated at £15,500, though the veterinary practice has capped her personal contribution at £4,500. She has launched a fundraiser to help cover these costs, with any excess funds to be donated to the clinic.

Hertfordshire Police confirmed they are investigating the circumstances surrounding the reported exposure of pet animals to a substance. A 32-year-old woman was arrested in connection with the incident and has since been released on bail pending further inquiries. The police stated that one cat died, while two cats and a dog were treated and have recovered. Investigations into the cause of death are ongoing. Authorities are working with partner agencies to establish the full details of the incident.

Courtney has expressed concern about the safety of her home, as the contaminated area has not yet been declared safe, preventing her family from leaving. She described the situation as 'horrendous,' noting the distress to her children, including nightmares experienced by her three-year-old daughter.
