Common conditions of pet rodents include respiratory diseases, gastrointestinal problems, dental problems, and cancer. Diseases of the skin may cause itching, hair loss or flaky skin in rodents. All rodents have teeth that grow continuously throughout their lives. Occasionally, these teeth grow too long and cut into the gums, causing pain when eating. Cancer is often seen in pet rodents, especially mammary (breast) tumors in rats and mice. Rodents with signs of respiratory or GI disease or evidence of a tumor should be seen by a veterinarian who can properly diagnose and treat the underlying condition.
