Why Do Cats Eat Grass?
by: Drew Pilton
Some cat owners make the mistake of preventing their cat from eating
grass. There are various reasons for this, one being that they think
it makes their cat ill or upsets their stomach. This is an incorrect
assumption and in fact the eating of grass followed by regurgitation
is a perfectly natural behavior for all cats.
Cats do not possess the ability to separate meat from fur bones or feathers
before eating like we do so they have to eat the digestible parts along
with the indigestible parts. When the cat has finished digesting what
he can the rest has to be removed from the system. To try and pass this
through the digestive tract could cause obstruction and severe illness
so this is where grass eating comes in.
The habit of eating grass triggers the natural process of regurgitation
of indigestible foods including its own fur balls which would otherwise
obstruct the system. This can appear to us humans as if the cat is being
violently ill but this is not the case and in fact is very beneficial
to the cat.
What about other plants and vegetables?
Cats cannot produce the enzymes needed to break down plant matter. Even
when pureed or powdered, vegetables simply pass through the digestive
tract without leaving any of their nutritional content. This alone is
not harmful to your cat, but when undigested plant matter mixes with
highly digestible food such as meat, indigestion and other complications
may occur. Grass is an exception however; some cats compulsively eat
grass when you leave them outdoors. This will cause them to regurgitate
the indigestible matter, including raw vegetables.
If your cat is unable to get access to grass he may attempt to eat your
house plants instead. This could be dangerous because some house plants
and flowers are toxic to cats, so if you have a house cat like a Ragdoll
cat for example you should provide a regular supply of potted grass
to prevent him looking elsewhere. And most importantly do not punish
your cat for regurgitating on to you carpet because he will not know
why you are punishing him. Regurgitation is an involuntary action of
your cat’s stomach so he could not stop it happening even if he
tried. Cleaning up after the occasional regurgitation should be an accepted
part of being a loving cat owner as they are only doing what comes naturally.
