Cuttlebone and mineral blocks: which one does your bird need?
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Cuttlebone is the basic mineral supplement for any cage bird: it supplies highly absorbable calcium and helps keep the beak in trim, all for a trifling 1 to 3 € apiece. Mineral blocks, harder and enriched with trace elements, complement it — especially for budgies and cockatiels that love to gnaw.

What does cuttlebone actually do?
It is the internal shell of the cuttlefish, made of more than 85% calcium carbonate. The bird scrapes at it on demand, according to its needs: laying hens, growing youngsters, birds in moult. The pecking also wears down the beak tip, curbing overgrowth — a genuine mechanical complement to natural wood perches. A cuttlebone left permanently in the cage carries no risk of overdose.
Cuttlebone or mineral block: do you have to choose?
The two are complementary rather than rivals:
- Cuttlebone: pure calcium, soft texture, accepted by nearly every species; replace it once soiled or two-thirds used up.
- Mineral block: harder, enriched with iodine, iron and trace elements, ideal for hookbills that love gnawing; expect 2 to 6 € each.
- Soluble grit: useful for canaries, offered in a small separate dish.
- Mounting: always at perch height, with the supplied clip or a stainless steel tie, never lying on the cage floor where it gets fouled.
How can you tell if your bird lacks calcium?
Soft-shelled eggs, difficult laying, tremors, easy fractures or frantic scraping at a freshly installed cuttlebone are all warning signs. A confirmed deficiency cannot be fixed with cuttlebone alone: see an avian vet, who will prescribe a dosed liquid supplement. Deficiency is often worsened by a lack of UVB, essential for calcium absorption: see our guide to UV lamps for indoor birds.
Which pitfalls should you avoid when buying?
Avoid cuttlebones gathered on the beach without treatment (salt, pollutants): boil them for 10 minutes then dry them, or buy them ready to use. Also beware of brightly coloured, sugary blocks, closer to a treat than a supplement. Our selections are gathered in the bird food category of the bird hub.
Frequently asked questions
My bird never touches its cuttlebone — is that a problem?
No, as long as its ration is balanced. Try scraping it in front of the bird to release a little powder: novelty often sparks interest.
How often should the cuttlebone be replaced?
Every 1 to 3 months on average, or immediately if it is soiled by droppings or water.
Is a mineral block enough during egg-laying?
Rarely. During laying, double up on cuttlebone and watch the hen; at the first sign of egg-binding, head straight to an avian vet as an emergency.
