Indoor plants not only add up to the aesthetic sense of the house but also feels like you are living with nature. It freshens up the air and soothes eyes as well as thoughts.

But before buying or getting plants it is very important to know about the plants and its compatibility with your pets.  That is if you have a pet in your house you should check whether the plant you are buying is safe for your pets or not.

Cats have a very inquisitive nature they like to know their surroundings and are very curious about things present the house. therefore It is necessary to have plants that are cat-friendly as we all know cats like to nibble grass or other small plants. Although the reason is unknown why they do this.

Some believe that eating grass helps cats in their regular bowel movement by acting as a laxative. Another theory is that eating grass helps in relieving the upset stomach from either fur or bones or feathers. As cats do not have digestive enzymes for the grass.
