How to Tell If Your Cat's Rear Quarters Are Healthy
Vomiting: Vomiting (sometimes accompanied by diarrhea) can be a sign of several diseases and conditions, including hyperthyroidism, kidney disease (acute and chronic), pancreatitis, and ingestion of toxic human foods, plants, or other substances. Diarrhea and vomiting can indicate an intestinal problem, such as IBD (Inflammatory Bowel Disease) or even cancer.1
Rapid weight loss: Sudden weight loss is always a red flag and when combined with vomiting, can be a sign of the diseases and conditions mentioned above. In overweight cats, rapid weight loss can lead to a serious condition called hepatic lipidosis (also known as fatty liver disease).2 While potentially fatal, hepatic lipidosis can be cured if caught and treated soon enough.
Butt-scooting: When a cat scoots its butt across the floor, leaving behind an extremely stinky brown substance, it is most likely caused by infected or impacted anal glands. Cats may also spontaneously express their anal glands when surprised or upset. Impacted or infected glands require veterinary treatment. Scooting may also be seen in cats with intestinal parasites.3
