Penn-Plax Bird-Life E-Cuttlebone Natural, 1 Pack (2 Counts) - Durable, Less Brittle Cuttlebones Enriched with Omega 3, Honey & Vitamin B1 - Easy Mounting, Cage Clip - Great for All Bird Sizes - White

I buy these for my turtle and she really loves them. No plastic backing to take off. I feel they are also a good value for a great product. Best cuddlebone I’ve purchased for her yet.

Unlike other cuttlebones, these don't quickly break apart. My parakeets love these.

This is a great product and my birds really love them! Can’t beat the price either! I would rather buy them from here than buy them from the pet store because I know I can get more for my money!

Personally I don’t think these should be called cuttlebones, as I bought them by mistake. There should be something right in the description that says they’re a compound including less than half cuttlebone material. That being said, I am here today to revise my review. I have raised it by one star, to a respectable 4 stars. The reason for the change is that once they got the hang of it, and figured out how to attack it, the birds did like these. It was not what they were used to. They barely touched it for the first two days. But then the third day, when I came home from work, I found that they had eaten so much of it! So I am still not sure of the other ingredients, and I still think the description itself should indicate that they are not "Natural cuttlebone," which they clearly are not, and which the description clearly says they are. I think this is just wrong of the seller to do this, and I don't know why it's allowed. Nevertheless, it is a treat that my birds have come to appreciate. The original review: They are very hard, not flaky or crumbly, and my nine budgies are still waiting for the real thing. They’ve barely touched it. It’s not a substitute for actual cuttlebones, in my opinion, but perhaps a supplement. I am still left in the situation of needing to buy some cuttlebones. I do understand and somewhat appreciate to ecologically oriented statement from the seller regarding the over-consumption of cuttlefish... what else is new, when it comes to humans? I doubt that providing cuttlebones for our caged birds is the major driver of cuttlebone consumption on the planet, however; we just have to be sure that all the parts of animals that are consumed for one purpose get used as much as possible for other purposes as well. In short, these “might” be liked by your birds as something different, with lots of good minerals etc. but it might be a bit like getting your kids to eat their vegetables. They still want – and perhaps need, for beak conditioning and what not – the cuttlebone.

This 2-pack of cuttlebones was perfect for my particular use, even though one of the pieces arrived cracked. The crack wasn’t an issue because I used them in an aquarium, but those using them in bird cages may prefer uncracked pieces. I used the cuttlebone in my aquarium to add calcium carbonate to the water to help support my aquatic snails shells.

This is made from cuttlefish bone powder, not a full cuttlebone. It will give the birds what they need, but I prefer the bone. The holder is not easy to use. I am glad I had a big plastic holder where you just stick them in and secure them. I am not yet convinced of the quality. I will have to see I just put it in their habitat. I am wondering about thw durability as well. It seems like it would crumble easily. I do have a senior bird and I think this consistency might be better for him. We will see.

It’s awesome my pancho loves it

My parakeets love them.

I read that these are also good for gerbils to chew on, gives them a little calcium boost - I bought this for a poorly furry who hurt his leg (possible fracture) thinking the extra calcium would do him good. Can't say for sure that the cuttlefish cured him, but he's all better now and he and his brothers have really enjoyed chewing on them!

My parakeets love these and I love the way they come in a package of 6 so I can stock up. They are good size solid cuttle bones.

Bigger than I expected! My cockatiel was intimidated by the size of the cuttlebone when I first put it in the cage, but has since quite enjoyed pecking away at it. Will last a long time.

An expensive price, yet can't be replaced for the damage!? One of the cuttlebones is clearly broken in half..

My friends Rainbow Lorikeet loves them.
