Great information from the about cats site:
Destructive Chewing by Cats
Destructive chewing by cats is undesirable, first, because of the potential of danger to the cat, and second, because of damage to family valuables. Causes of destructive chewing by cats can range from teething in kittens to curiosity, to boredom, and even (surprise!) because of a nutrient deficiency. Kittens, like human babies, explore with their mouths, and these habits carry through to adulthood.
We’ll explore here the kinds of things cats typically chew, possible causes, and ways to prevent destructive chewing.
Wires and Cords
Chewing on these cords poses hazards to your cat, from minor shock to death. Cats primarily chew on cords out of boredom, especially if left alone during the day. Try to provide plenty of “play-alone” toys for your cat or kitten, including wall or door mounted toys they can swat or bat around, cat towers to explore, with attached toys for added interest, even an arrangement of cardboard boxes on the floor to form a tunnel, with holes cut through the sides.
To handle the cord situation itself, you need to devise a way to cover the cords, discourage access to them, or make them unpalatable for chewing.
- Cover the cords: Many computer supply stores carry pre-split hollow tubing for covering cords and electrical wires, as well as kits for managing computer cords. If you’re handy with a utility knife, you can purchase flexible poly tubing in several diameters, in most building supply or hardware stores. Slit one side of the tubing, then cut it to length for each cord. You might also try larger “corrugated” tubing to run several wires through, if that works for you.
- Discourage access to the cords: Try applying several rows of double-sided sticky tape to the floor surrounding a large cord tangle (such as frequently happens with computers). Cats will be reluctant to walk across the tape. Another excellent tool for keeping cats out of any undesirable area is the SssCat! cannister by Multivet. This product is a three-pronged training tool which works with a motion detector atop the cannister which triggers a high-pitched alarm and a quick spray of harmless material. It’s a lot more expensive than bitter apple spray, but well worth the cost in its versatility for training purposes.
- Make the Cords Taste Bad: By far one of the best training tools for any kind of destructive chewing is bitter apple spray. It is guaranteed to leave a bad taste in your cats mouth, one that he won’t long forget.
Cats have a natural desire for greenery to chew, and your live houseplants might become a target. Some of these plants can be extremely toxic to cats, and for your cat’s safety you need to learn to recogize and get rid of these plants. Check this list to see if any of your house plants are on it, then either discard or make completely unavailable those plants. For other plants, try the bitter apple spray or the Ssscat! product.
Fabric and Leather Chewing
Some cats will chew on fabric – wool is often favored for unknown reasons, and often by Siamese Cats and other oriental breeds. It’s also possible that cats will chew on soft surfaces because of an innate need to nurse, usually because they were either weaned too early or were adopted as tiny kittens as orphans. Our Jaspurr was adopted at 6.5 weeks, along with his littermate, Joey (the owner of their mother cat wanted them “out of here”). They had been partially weaned by the mother cat, and Joey adjusted easily. However, Jaspurr developed a “nursing” habit, using his right front forearm as the target, that continues today at 18 months. It could be because he was the last born, and as a baby was the smallest kitten (the “hind-teat” syndrome).
For whatever reason, it gives him comfort, he only does it when lying close to one of us, and it has not caused any skin irritation, so we allow him his little idiosyncrasy.
For the kind of chewing behavior we’re discussing here, the best way to discourage such behavior is to offer other ‘legal’ chewing sources for your cat, e.g. chewable soft toys. I’ve even seen wool mice, which might be a perfect substitute for your mohair sweater. Other cats will chew on leather gloves, or even shoes (rubber flipflops come to mind). Jaspurr loves to chew newspaper. He doesn’t eat it, he just rips off small pieces and spits them out, and soon is surrounded by newspaper confetti.
If you can’t put away all the fabric and leather items your cat likes to chew on, try the bitter apple spray on the area where he usually chews, but test it first on a small hidden seam.
A Word About Kittens’ Chewing
As mentioned above, kittens often chew because they are teething (around three to six months). All of the methods described above will work, especially the toys, but there is one free tip that works wonders with kittens’ teething: plastic drinking straws, especially the large ones used for milk shakes. They provide the crunchy contact kittens need, and they make a great interactive toy. Some of my forum members will tie a loose knot in a straw to add interest, but I prefer to leave them straight. You can derive lots of interactive play by teasing your kitten with the straw, then let him “capture” it and watch him proudly carry around his “prey.” Our adult cats still remember their straws, and it’s not unusual to see one of them batting one around the floor.
Here’s to healthy, legal chewing for our cats!
