If your customer's bird insists on throwing ordinary food bowls to the floor then this is the solution. Designed so you can easily remove the bowl but still be completely bird-proof (there`s always one though!).
With its secure fixing the Parrot won't be able to spill any food onto the floor, meaning less mess for your customer to clean up so they can spend more time with their Parrot.
Bolt the holder securely to the bars on the bird's cage and then simply twist the cup to fasten or remove (don`t leave just the holder in the cage for long periods though).
