Exposure to pesticides and the toxins they contain poses a risk to cats and dogs year-round, but it is especially high in spring and summer when gardening activities increase.
Pesticides come in many forms and appear in a wide variety of household and garden products, often unnoticed by pet owners. Although most pets never suffer ill effects, each year several become sick through exposure, which can sometimes be fatal if untreated.
Read on to understand what pesticides are, which common products contain them, symptoms of poisoning, and practical steps to safeguard your pet.
Pesticides are chemical substances or microorganisms designed to deter, kill or neutralise pests and parasites. They have legitimate beneficial uses in pet care, such as flea spot-on treatments and mite control. However, they are most commonly used in gardening and agriculture to protect plants and crops from weeds, insects, and other pests.
Because pesticides disrupt pest nervous systems, they can adversely affect other animals, including cats and dogs, especially if ingested or absorbed in sufficient quantities.
Many garden and household products contain pesticides, including ant bait, slug pellets, weed killers, insect sprays targeting aphids or greenfly, and some fertilizers and bark chips.
Be cautious: labels stating “environmentally friendly” or “green” rarely mean pesticide-free. Always check ingredients carefully, especially for carbamates and organophosphates, which can suppress the nervous system and cause severe poisoning symptoms like seizures.
Direct ingestion by pets is unusual, but they can be exposed by eating plants or grass treated with pesticides, or by picking up sticks or toys from treated areas.
Walking or playing on pesticide-treated ground is the most common exposure, as toxins can transfer to the pet’s coat and be ingested through grooming. Cats are especially vulnerable due to their meticulous licking habits.
Symptoms usually occur within hours of exposure and include vomiting, diarrhoea, lethargy, abdominal discomfort, trembling, joint stiffness, seizures, and in severe cases, collapse.
If you notice these signs, consult your vet urgently. Bring any suspected pesticide product packaging with you to assist diagnosis and treatment.
If you suspect your cat or dog has come into contact with pesticides, act quickly:
Early treatment can be lifesaving, so do not delay.
By understanding pesticides and taking simple precautions, you can help keep your beloved pets safe while enjoying your garden and outdoor spaces responsibly.
