Birds can safely chew and shred plain paper, but actually swallowing large amounts is a different story. Small bits of plain newspaper or paper towel that get ingested during play are generally harmless. The real risks come from eating too much at once, or from chewing paper that contains coatings, dyes, or adhesives.
Most bird owners encounter this question because their parrot, parakeet, or cockatiel loves tearing paper apart. That shredding behavior is normal and healthy. The concern is what happens when pieces get swallowed instead of just tossed around the cage.
Why Birds Shred Paper
Paper shredding is a natural extension of foraging behavior. In the wild, birds tear apart bark, leaves, and seed pods to find food or build nests. In captivity, paper gives them something to work on with their beaks, which is important for mental stimulation. The ASPCA lists plain shredded paper and empty toilet paper tubes among safe household materials for bird enrichment, and suggests hiding treats inside homemade paper puzzles to keep birds occupied for hours.
The goal is shredding, not eating. Most birds tear paper into strips and drop them. Some will ingest small pieces in the process, which is usually fine. The problem starts when a bird is actually consuming paper rather than just destroying it.
What Happens If a Bird Swallows Paper
Birds cannot digest cellulose, the main component of paper. A few tiny fragments will pass through without issue, but larger quantities can clump together and form a blockage in the crop (the pouch at the base of the throat where food is stored before digestion) or further along in the intestinal tract. VCA Animal Hospitals specifically warns that shredded and recycled paper bedding is “not digestible and can cause impaction or obstruction of the gastrointestinal tract if ingested.”
The difference between cage liner paper and bedding matters here. A thin sheet of newspaper lying flat on the cage floor offers little opportunity for a bird to tear off and swallow large pieces. Fluffy shredded paper bedding, on the other hand, gives birds easy access to mouthful-sized pieces they’re more likely to consume in quantity.
Signs of Crop Impaction
If a bird has eaten enough indigestible material to cause a blockage, the crop will still feel full first thing in the morning, before the bird has eaten. Normally the crop empties overnight. An impacted crop feels hard, similar to a golf ball, and won’t shift or compress when you gently massage it. The bird may also seem lethargic, lose interest in food, or produce fewer droppings than usual. If the crop stays full even after you withhold food for several hours and offer only water, that’s a strong sign something indigestible is stuck.
Which Paper Types Are Safe
Plain, undyed paper is the safest option for birds to interact with. This includes:
- Newspaper: Modern newsprint is free of lead and non-toxic to birds, even if they chew on it. While newspaper ink historically contained heavy metals, those have largely been replaced with organic pigments. A USDA analysis found that cadmium, chromium, mercury, and lead levels in newspaper were well below safety guidelines and comparable to levels found in plain straw or wood shavings.
- Plain white paper and paper towels: These are among the most commonly recommended cage liners by avian veterinarians.
- Unbleached butcher paper or kraft paper: Simple, uncoated, and free of dyes.
- Empty toilet paper and paper towel rolls: Great for foraging toys, as long as you remove any remaining adhesive strips.
Paper Types to Avoid
Not all paper is created equal. Several common types carry risks that plain paper doesn’t.
Glossy or coated paper. Magazines, catalogs, and packaging often have coatings made from plastics or aluminum to improve moisture resistance and print quality. These coatings don’t break down the way plain paper does and introduce materials you don’t want in your bird’s digestive system.
Thermal receipt paper. The kind of paper used for store receipts and some fax machines relies on a heat-reactive chemical coating rather than traditional ink. Avian nutrition experts at Lafeber Company specifically flag thermal printer paper as something to keep away from birds.
Heavily dyed or printed paper. While a small amount of modern newspaper ink poses minimal risk, paper saturated with colored inks (like glossy advertising inserts or wrapping paper) contains more pigment and potentially more chemical residue. Stick to plain or lightly printed paper.
Cardboard with visible glue. Plain cardboard itself is similar to thick paper, but the adhesives used to assemble boxes and packaging deserve caution. The most common glue in cardboard products contains a compound called polyvinyl acetate. While it’s considered non-hazardous for humans, a veterinary case report involving a parakeet found evidence that this adhesive is potentially toxic to birds. The report noted that a lack of safety data for birds should not be interpreted as proof of safety. If you give your bird cardboard to chew, choose pieces without visible glue seams or residue.
Keeping Paper Play Safe
The simplest approach is to let your bird shred paper freely while watching for signs that it’s actually eating the pieces rather than discarding them. A bird that consistently swallows what it shreds needs the paper removed or replaced with a different enrichment activity.
For cage lining, lay a flat sheet of newspaper or paper towel across the bottom and replace it daily. This setup lets you monitor droppings easily (another reason avian vets recommend it over bedding) and limits how much paper a bird can pull up and consume. Avoid piling loose shredded paper on the cage floor, since birds are far more likely to ingest material they can easily grab in beak-sized pieces.
When making foraging toys, wrap treats loosely in plain paper or stuff them inside a toilet paper roll. The bird works to get the food out, gets the satisfaction of shredding, and typically ignores the paper scraps once the reward is gone. Observe your bird the first few times you introduce any new material to make sure it interacts safely.
