Cats confuse their owners by ending grass-grazing with regurgitation or vomiting. The reason for this predictable behavior is unclear, but it has been suggested that our pets eat grass, at least sometimes, in order to stimulate vomiting. Relief from hairball indigestion may be one motive for plant eating in cats. However, not all plant-eating leads to getting "sick", so it is a good idea to consult with your vet if the pattern continues.



Because of this tendency to seek and ingest vegetation, cats may naturally experiment with the taste of houseplants. Such behavior can be undesirable, at best, or dangerous when leaves or other plant parts are toxic.

To keep your cat safe, be sure all plants in your home are safe in case of ingestion, or place them out of reach. Hanging pots, for example, usually lose their appeal even to curious cats. Non-toxic, valued plants can be protected with a small amount of sprayed vinegar or black pepper solution on leaves.

As a gift to those cats that seem determined to eat plants, owners can offer treats of herbicide- and pesticide-free potted grass. Grass seeds or even parakeet seeds can be sprouted in seedling pots and offered occasionally, the empty pot then re-seeded for a new batch. In small amounts, grass can be a welcome treat for any house cat.

Listed here are plants poisonous to cats that must be avoided if there are cats in your home. While in some cases just parts of a plant bark, leaves, seeds, berries, roots, tubers, spouts, green shells might be poisonous, this list rules out the whole plant. If you must have any of them, keep them safely out of reach. Should your feline friend eat part of a poisonous plant, rush the cat to your veterinarian as soon as possible. If you can, take the plant with you for ease of identification.
