Plants Poisonous to Cats

Plants Poisonous to Cats

There are many substances that prove to be toxic to all mammals. In the same way, plants that are poisonous to cats tend to have some or the other effect on the animal's health. These plants include many different types of botanical species such as house plants, indoor plants, and also a huge range of wild plants.
All mammals, including humans, dogs, and cats, need many different nutrients that are present in green plants, especially the leaves. Sometimes, you might notice your cat or dog chewing on the leaves of some or the other plant. Mammals like cats chew on these plants in order to consume some important nutrients such as fiber, vitamins, etc. The feline family has a habit of chewing on the leaves of plants that are kept indoors. The drawback of this habit is that there are some plants that have substances which are toxic to almost all cats.

At times, the chemical insecticides and other pesticides that are sprayed on the plants also tend to be toxic to cats. Many cat owners have discovered indoor and outdoor plants that are not poisonous to cats, having fatal effects on their pets due to the pesticides and insecticides. One of the best solutions to keep the cats away from these plants is to spray some diluted lemon juice on the leaves, as most cats hate the smell and taste of the lemon juice. It is also very important to cover up the soil of the plant with a wire mesh.

While selecting plants for your garden, you must exclude the following as they have proven to be fatal to many cats.

Your cat, at the same time, needs a lot of nutrients that are present in the parts and leaves of these plants. Hence, many pet shops have started providing cat owners with a potted plant that is known as 'cat grass'. Cat grass is basically a plant that contains all the nutrients, like fibers, vitamins, and minerals, that are needed by the cats. It is better to have cat grass which can be kept as an outdoor or indoor plant. Plants that are poisonous to cats are not always fatal and at times, the cats themselves eject the toxic substances through vomit.
Now that you know the name and description of outdoor and indoor plants that are poisonous to cats, you can keep your feline friend away from these. A precaution that you must follow while purchasing any plant from the nursery, is to confirm whether it is poisonous to any pets or not.
