There are a few different reasons as to why your cat may take a shine to plastic. One of the most common is an affinity for plastics or shower curtains and investigating them. Whatever the type of plastic your moggy favours, you’re likely to find that it’s not an uncommon behaviour in other cats too.
They Could Mistake it For Food
There is a theory that plastic might just retain some of the taste of animal fats and proteins. Plastic usually contains some form of animal derived products so it’s no surprise that our moggies take an extra special interest in them. The smell of the plastic might be alluring to them and when they do lick or bite into it, either the taste or the sensation of it crinkling beneath the force of their teeth can be just as satisfying as it is tasty.
They’re Practicing Hunting
For softer plastics like carrier bags, there could be a chase element involved where the movement of a bag caught in a breeze can look strikingly similar to hunting prey. Many cats, especially indoor cats will never get the real sensation of hunting prey and catching them, so a carrier bag may be the next best thing.
Cats love to chase, that’s no secret. They love to pounce after soft toys and chase them if you dangle a feather on the end of a string. If your moggy is used to playing these kind of chase and catch games then they are more likely to take an interest in anything that moves in a similar way. You might catch them trying to catch your shower curtains if they’re caught in the breeze!
They Have Nothing Else to Do
Curiosity can get the better of cats quite easily and have them investigating things that aren’t beneficial. Without plenty to do to keep them from getting bored, they may resort to making their own entertainment which can come in the form of licking or eating things they shouldn’t.
Eating plastic can provide a form of mental enrichment if there is none to be had which can quickly form into a bad habit. If it’s allowed to develop, it can become more rewarding than other forms of mental enrichment. Giving a cat toys and food when they have already developed a liking for eating plastic can be futile and you have to manage the issue heavily before you see any improvement.
Medical Issues That Cause Cats to Lick or Eat Plastic
While eating plastic is not often linked to medical issues, there are a few cases where it can be linked. Any illness that causes the appetite to rise radically such as undiagnosed diabetes or if they’re on a course of steroids to help treat an ailment, eating plastic can be a result of just feeling hungry all the time.
In cases of inflammatory bowel disease, it has also been reported that some cats may try to eat plastic as a means of trying to access nutrients when their intestinal tract is struggling to obtain hem. On some rare occasions, cats with dental issues may also resort to chewing and licking plastic to try and relieve any pain from their mouth.
