It's a familiar scene: you hear a rustling from another room, and when you peek in to investigate, you see your feline friend chewing on a plastic bag, again. You're probably wondering why your cat likes to eat plastic and how you can divert your kitty's attention away from the potential dangers that go along with it.

Why Plastic?

Why does my cat try to eat plastic bags? Essentially, because they like it. Plastic bags appeal to your cat's senses for a variety of reasons: the crinkle of the plastic, the smell of the food that was contained in it wafting through the air, the smooth surface under their paws. It's a full sensory experience for your little pal.

Kitties also find plastic bags especially alluring, explains the Pet Health Network, because "many bags are also coated in substances such as cornstarch, [and] stearates (salts of stearate acid), or are made of animal by-products such as gelatin, which makes them attractive to cats." Your cat sees a plastic bag and thinks, "Oh, look, a treat!"

Likewise, your cat may chew on bags and other, harder plastic objects, such as straws and milk jug rings, to alleviate anxiety caused by environmental or medical stressors. These can be anything from moving to a new home, a new pet or a new baby in the house, or even illness and ageing.

Safety and Prevention

Cats and plastic bags are a potentially dangerous combination for a few reasons. In addition to swallowing a foreign object that may obstruct their airway or cause intestinal distress, your cat could get the plastic handles wrapped around their neck, which could cut off their breathing.

The safest way to prevent these types of accidents is to keep plastic bags out of your cat's reach at all times. Stash extra bags in a closet, the garage, or another cat-free space. This may not be an option, however, if you use the bags to line rubbish cans or even their litter box (although you probably don't have to worry about them chewing on a little pan liner because since most healthy cats do not associate their litter box with snack time). If you can't close off the room with the rubbish can, invest in a can with a lid that you can tuck the bag under. They can't chew on it if they can't reach it. This motto goes for other harmful playthings, including electrical cords.

If you suspect that something beyond sensory satisfaction is going on, make an appointment with your veterinarian to find out more about the burning question of why your cat is eating plastic. They can rule out any underlying medical conditions such as pica, a disorder that causes animals to eat non-food items such as plastic, rubber, or fabric, says the Animal Behavior College. Pica also could indicate a more serious illness, like feline leukaemia. So, it's a good idea to get your kitty checked out as soon as possible.

Plastic Alternatives

Separating cats and plastic bags is achieved by stealth diversion tactics. If removing the alluring object from their reach isn't an option, offer them something more desirable. Stimulate their senses with toys like food puzzles or ball mazes. Because their hunting instinct runs deep, they will appreciate soft cat toys that they can chase around the house. Many cats also appreciate dog toys, particularly the sturdy, durable stuffed animals.

Another option to break up cats and plastic bags is to give your feline pal their own safe chewing spot. Create an area where they can chew on cat treats or toys to their heart's desire. Having their own garden is a healthy, fun alternative to unhealthy and potentially dangerous plastic.

Cat parents can add eating plastic to the list of weird cat behaviours . It's their idiosyncrasies that make kitties so lovable. Just make to discourage snacking on plastic, curb the behavior with safer alternatives, and visit your vet to get to the bottom of their chewing habits.
