Many pet owners choose to allow their cats to roam free outside. During the summer months, however, it may be necessary to treat the weeds on your property. If you choose to use a chemical weed killer, be sure to keep your cat safe from the chemicals. Many of these chemicals are harmful to cats, especially if the cat munches on the weeds that have been treated.
Pour boiling water over the weeds in your lawn that you wish to kill. The water will not injure your cat in any way, and will protect it from chemical weed killers.
Combine 1 qt. vinegar and 1/2 cup lemon juice in an empty spray bottle to create an organic weed killer that is safe to use around cats. Spray the weeds with this solution instead of a chemical herbicide.
Call your cat indoors before you use a chemical weed killer. This is the only way to keep your cat safe if you go the herbicide route. Keep your cat indoors for the length of time specified on the herbicide container. Usually, this is until the weed killer has dried, or until you have watered your lawn. Walk your cat on a leash in a park until your yard is safe for your cat to play in again.
Store leftover herbicides in a locked garage or shed. Place them on the top shelf in case your cat gets into the garage or shed.
