61 Houseplants that are Poisonous to Your Cats

Of all the house pets, cats are more prone to fall prey to mishaps thanks to their innate curiosity. So the onus of ensuring that plants in the house do not have any adverse impact on your feline friend rests with you.

A growing fad in the realty zone is decorating one’s house with attractive foliage because there are a lot of health pluses to the same besides the freshness and colour which they add to one’s interiors. But pet owners need to double-check if any of these seemingly innocuous plants have a serious or sometimes even a fatal effect on their feline friend.
