It is extremely harmful to both cats and plants.
* Cats: Ammonia is highly toxic to cats. Even small amounts can cause respiratory irritation, eye irritation, vomiting, diarrhea, and even death.
* Plants: Ammonia can burn and damage plant leaves, potentially killing the plant.
Safe Alternatives to Keep Cats Away from Plants:
* Citrus peels: Cats dislike the smell of citrus, so placing orange or lemon peels around plants can deter them.
* Peppermint oil: Diluted peppermint oil sprayed on plants can also be effective.
* Commercial cat deterrents: There are many commercially available cat deterrents that use safe and effective ingredients.
* Physical barriers: Using netting or fencing around plants can prevent cats from accessing them.
* Plant selection: Choose plants that cats are less likely to eat, such as those with strong scents or bitter tastes.
Remember, your cat's safety and the health of your plants are paramount. Always choose safe and humane methods to keep cats away from plants.
