Grass includes many lawn and field species with narrow blades, found in yards, parks, and pastures. Pets may nibble it outdoors or from indoor trays sold as cat grass. Plain untreated grass provides little nutrition, but small nibbles are usually tolerated by healthy pets.
The main risk comes from what is on the grass rather than the blade itself. Herbicides, fertilizers, slug baits, and weed-control products can leave residue after treatment. Fresh clippings may also carry residue and can clump in the stomach if large amounts are swallowed quickly.
Lawn edges, garden borders, and recently treated patches are common exposure points. Morning dew or irrigation can spread surface chemicals across nearby blades. This is why treatment timing and cleanup matter in pet yards.
For pets that like to chew, use untreated indoor cat grass or clean unsprayed areas only. Keep pets away from treated lawns until labels say it is safe to re-enter.
