Eating Houseplants
Most cats mill want to chew on houseplants, so avoid toxic ones. Provide grass in pots or non-toxic plants such as the spider plant for safe chewing.
Plants with toxic or irritant effects (often, but not always, noted on the label) and those with sharp spikes are best avoided.
If cats tip plants over when exploring them, or scratch in the top of the pot, try placing large, heavy pebbles on the surface of the potting mixture.
