Penn-Plax Bird-Life (BA655) Natural E Cuttlebones | Enriched with Omega 3 and Vitamin B1 | Great for All Birds | 2 Cuttlebone Treats per Package

got these for my baby red eared slider—about 3 months old—and she seems to love it! she’s been going back for little nibbles every now and then. i broke off about 1/4 and stuck it in her tank. beware this isn’t real cuttlebone, it’s made from cuttlebone powder.

I bought these for my aquatic pets. Since we didn't need an entire bottle bone we opted to break one into pieces and for them in. They broke easily for me and I was able to control the sizes I wanted to break it into. I've used these before so the thickness was as expected. They appeared white but looked to be a bit flaky as well. Not a negative for my interested use. I didn't notice a small at all.

Birds love it

It will do the job, but It didn't taste any strawberry or banana... (yes. I tasted it)

Exactly what you expect, same as you'd get in a pet store, just less expensive. They are individually wrapped. One was broken, but I think I did that taking it out haha.

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.

I got these to break into small chunks to give to our hermit crabs for calcium. They're nice & dense and last a long time.

These are fine.
