Why Does My Cat Eat Weird Things?

Cats are pretty savvy about knowing what they should—and shouldn't—eat, so pay attention when your feline starts snacking on stuff that isn't food. Sometimes it signals a bigger issue.

Medical problems: Bring your cat in for a vet check if you notice sudden changes in appetite. For example, an increase in appetite may be a sign of hyperthyroidism in older cats. And eating litter may be a sign of anemia.

Behavioral condition: Cats can have compulsive disorders, where they eat things other than their food or groom obsessively, which causes skin problems. In these cases, seek out a board-­certified veterinary behaviorist.

Genetics: Siamese or Birman purebreds are more likely than mixed-breed cats to suck and chew on wool. This can be a serious problem—eating strings could tangle your cat's intestines.

Boredom: Indoor cats may eat odd things for entertainment, such as shoelaces, ribbons and tinsel. Offering puzzle toys, games and playtime can help.
