The big birds are tough sometimes.

The Smart Crocks are guaranteed against damage with a registration card included with each crock.
I have just contacted the company and they state they are made of a polystyrene/acrylic resin. We will add the material to our listings.
These dishes are also supposed to hold up well against the stronger birds.

They should fit most all bird cages. The stainless one fits barred cages fine with 4 bolts
If you have used the Booda perches then you may be familiar with the attachment piece, they fit straddling the cage bars with a twist on plastic cap in the rear.
I hope this information helps.
