cuttlebones are essential, especially to breeding birds. but i hate those metal holders that they come with! often, they don't stay attached to the cage or the cuttlebone and if they do, they will eventually break because the metal is so flimsy. sometimes, they don't fit with the width of the cage bars and you have to buy a cuttlebone holder (which I highly recommend) to mount them in the cage.

Pros: all the benefits of your typical cuttlebone

Cons: the metal holders are usually useless

These are great, and my birds would tear into these things in a day and have all these little bits on the cage floor.

The texture is quite soft, so it gets used up fairly quickly.

Somehow even though it has calcium, there are other nutrients in it that result in thin shells for the eggs. Do not give these when you have a bird that is laying eggs that are probably fertile. A mineral block is a better during this period, if you want to have the babies.

Pros: Fun for birds to bite at, provides minerals

Cons: Can cause eggs to have week thin shells

Great for your little parakeet or canary, these attach easily to your cage and last for a really long time. Pennplax makes yet another good product with these.

Pros: Pennplax makes a good cuttlebone.

Cons: Non found.

9 times out of ten,I would be in the bird cages trying to figure out a way to keep the cuttle bone from falling out of the metal clip,and eventually,I'd get something to work.You can't complain,the price is great,the birds need it and it's replaced frequently enough to where it's not worth sweating over.The price is right!

Pros: price is good healthy for birds

Cons: the metal tie was always a challenge

All birds need cuttlebones for the good of their beacks and the extra minerals they get. But those flimsy metal clips don't hold the cuttlebone on the cage. It is better to buy a seperate cuttlebone holder, and just discard the metal clip.

Pros: great for birds beaks, and they are also a treat

Cons: Those flimsy metal clips don't hold the cuttlebone.
