Can hamster urine have ammonia in it?

Yes, hamster urine can contain ammonia, especially if it is concentrated or if the bedding is not changed regularly. Ammonia is a byproduct of protein metabolism, and when urine breaks down, it can release ammonia, which has a strong odor. Proper hygiene and regular cleaning of the hamster's habitat can help minimize ammonia levels and maintain a healthier environment for the pet.
