Key differences between cats and dogs

Lilies: true lilies and daylilies cause kidney failure in cats, even from pollen or vase water, but are not kidney-toxic to dogs.
Essential oils: cats are more sensitive to plant oils (lavender, eucalyptus, mint, citrus) because they lack some liver enzymes that break them down.
Bulbs: dogs dig, so they are more likely to eat tulip, daffodil and hyacinth bulbs, the most toxic part of these plants.
Grazing: both species chew plants out of boredom or curiosity. Cat grass and chew toys are safe outlets.
