Dear Marie,
My cat is weird! He likes to lick and/or eat
plastic. When I go shopping and bring the groceries in, he can’t
wait to lick the plastic bags. He wakes me up in the night or early in
the morning with his constant licking of the plastic liner over hanging my
bedroom trash basket. He chews on plastic wrappers, plastic ribbon,
and anything else plastic he finds. I’m not talking about food
wrappers either – although if those are plastic, he likes them equally
well. But it’s not the food scent that’s getting him all worked
up. It’s the plastic! Occasionally, he gets his paws on my
photographs and licks and chews them. This is especially upsetting
because he has ruined some of my favorite photos. Sometimes his plastic licking
goes on for hours. Is my cat just a freak or do other cats do this too?
Tracy
Dear Tracy,
You are not at all alone. Many cat owners report the
exact behavior exhibited by your cat in their own pets and they are just
as baffled. Though the attraction to plastic varies in degree
from individual to individual, it is not at all uncommon for cats to lick,
chew, and even eat plastic.
Cats who seem to be most obsessed with plastic are often the
type of feline who may still try to “nurse” as an adult (sucking on
blankets, or their people’s clothes, etc.) or are otherwise
orally fixated. These are cats who were most likely taken or weaned
from their mothers at too early of an age.
One major concern relating to this behavior is that when
cats consume plastic, especially the decorative plastic grasses that line
Easter baskets and gifts, or plastic tinsel, they can become seriously ill
from resulting intestinal blockages. Consequently, you should try to the
best of your ability to keep your cat from ingesting plastic.
Many plastic products today are made with a number of
biodegradable components, including cornstarch. These ingredients
along with various petroleum products emanate an odor, undetected by people,
but irresistible to certain felines.
The texture of plastic also seems to be a factor in this
bizarre activity. It is speculated that many cats just enjoy the smooth,
cool feeling on their tongues. They also enjoy the sound that plastic
makes. (A cat's tongue on a plastic bag can be VERY noisy. I have
been awakened by my own cats licking plastic bags more times than I can
count!) This combined with the aroma, may give cats a very
pleasurable sensation akin to enjoying a lollipop that never gets any smaller
no matter how many times it gets licked.
I do caution you to keep all photographs safely stored away
in photo albums or behind glass frames. Some photographic processes use
chemicals that can potentially cause liver and kidney damage
if consumed. So please be very careful with these items.
Licking or eating non-food items may also be a sign of a
serious illness such as feline leukemia or other immunodeficiency
diseases. Just to be on the safe side, you should have your cat
tested. Most likely however, this behavior is nothing to worry about
as long as you restrict it to licking and not consuming.
If you feel you must stop your cat from continuing in his
plastic quest, you should first eliminate the type of plastic he targets
from your household environment. Next, increase his fiber intake
with specially formulated high fiber content pet foods. You can also
grow “kitty grass” indoors so that your little friend has something more
natural to chew on or lick.
Finally, some cats become addicted to plastic licking simply
because they are bored and don’t get enough stimulation. I would strongly
recommend getting some new toys for your cat and adding some extended playtime
to his daily routine. Give him a lot of extra affection or brush him more
frequently. If he is alone during the day and you work, perhaps you
should consider getting him a little feline buddy with whom to pass the
hours while you are away or busy.
