A pet cat vomiting might cause some concern to owners. When a foreign irritating substance is detected by the body, vomiting is the resulting reaction. If the vomiting becomes severe, it may be an indication of a health problem yet to be diagnosed. For cats, expelling swallowed hairballs is the simplest reason why they vomit. Cat vomiting is usually classified as chronic or acute. Acute vomiting usually lasts for several days and is usually because of toxin ingestion, urinary issues, indigestion, or an infection. Chronic vomiting, on the other hand, usually lasts for an extended time. If your cat is throwing up multiple times a day for over a week, it could mean she has some critical ailment like cancer, gastrointestinal illness, hyperthyroidism, or organ failure. Simple vomiting in cats might not always require a visit to your veterinarian. Although, if your cat is vomiting often and is doing so for over a week, you will want to take her to a veterinarian Bourne, MA for a diagnosis and for treatment. If your cat vomits for more then one day, immediately take her to the nearest pet clinic.
