Cat has eaten a massive amount of foreign objects

An operation to remove foreign objects from stomach of a cat. A massive amount of rubber bands and some plastic. This was not a starving cat. It is an owned cat. Only indoor cat. Female. 1,5 years old. Came to be neutered, but we discovered this in the pre-examination and another operation had to be performed. The owner had noticed nothing unusual the days before in the cat’s behavior. It was normal, happy, and playing. It is called Pica when a cat eats foreign objects.
