I would say probably not. They do come in different sizes, but the larger one is perfect for my sun conure. As cockatoos are significantly larger, I doubt it would be big enough. Sorry!

I got the small for my parakeet and it works just fine, but it would also work for Cockatiels and similar sized birds just as well. For larger birds, I think the larger size would work great. I've seen them in the store and I think it would work just fine for Cockatoos
