Why do cats eat grass? 🌱🐱
In the largest surveys of domestic cats to date, researchers found that approximately 71% of cats were observed eating plants, yet 91% showed no signs of illness beforehand. Only a minority vomited afterward.
So, if cats aren't eating grass because they feel sick, why do they do it?
Researchers currently believe grass eating is a normal, instinctive feline behavior inherited from wild ancestors. Plant consumption has been documented in wild felids and other carnivores, suggesting it serves an evolutionary purpose beyond simple nutrition.
Several theories exist:
• Grass may help stimulate movement within the
digestive tract.
• Insoluble fiber may assist with the passage of
ingested fur and other material.
• Historically, plant consumption may have helped wild
carnivores expel intestinal parasites.
• Some cats may simply enjoy the texture, smell, and
sensory experience of chewing vegetation.
Interestingly, studies found that young cats eat plants more frequently than older cats, and long-haired cats do not appear to consume more plants than short-haired cats, challenging the common belief that grass eating is primarily about hairballs.
For most healthy cats, occasional grass consumption is considered normal. Sophie certainly seems to enjoy "mowing the lawn."
* Make sure any plants available to your cat are feline-safe and free from pesticides, herbicides, rodenticides, and fertilizers.
