Overview

While some weed killers (also known as herbicides) are marketed as safe for cats, this depends on the chemicals used, application methods, and whether owners follow safety instructions. Cats can be exposed to weed killers by walking on treated grass, brushing against treated plants, or being hit by spray drift.

Swallowing toxic chemicals can also happen when cats groom themselves after contact, eat recently sprayed grass or plants, or drink contaminated water. They can also ingest the product directly if they come across a spillage, or an unsecured container.
