Watch out! These popular houseplants are bad for cats

Find out which houseplants are bad for cats

Why is it that our canine friends love and beg for whatever we eat, be it chocolate or cheese or whatever? While cats on the other hand have a penchant for plants. This may present itself in the form of nibbling on a leaf or petal. Some cats may go as far as de-potting a plant because they prefer the soil as cat litter. Although many cats snack on all sorts of house plants and nothing bad ever happens to them, keeping a safe home for your pet should be a top concern.

There is no arguing that plants, flowers, and greenery spruce up any place. These days you will be forgiven for wanting to grow an indoor jungle. Plants make us happy, they improve indoor air quality and have been known to reduce depression and anxiety. These same plants may also be potentially toxic to your feline companion. Knowing which houseplants are bad for cats will help give you peace of mind when you have a mischievous plant snacking creature in your house.

Why do cats enjoy snacking on houseplants?

We know that cats are carnivorous right? So why do they exhibit herbivorous tendencies toward houseplants that are bad for cats, you may ask? The following few points should help clear things up:

  • Cats are curious and intelligent. New additions to the home such as plants or flowers have interesting smells and need to be investigated. Nibbling allows her to test the plant as a possible food source.
  • Cats may chew on plants out of pure boredom or curiosity. The opposite may be true too. They may enjoy a nibble for the fun of it.
  • Grass or fibrous plant-eating may help to aid digestion in cats. They may also eat plants to induce vomiting after having eaten something that disagreed with them.
  • Cats that are anemic may often eat soil or cat litter to correct the lack of iron in their bodies. Non-toxic grass-like Alfalfa and Oat are great additions to a cat’s diet because it contains important B vitamins, iron, zinc, and selenium.
