In felines, Anorexia is not a disease; it is symptom of an underlying condition. Anorexia may begin as simply a decreased appetite, but ultimately the cat may refuse to eat a bite. If your cat keeps on to rejecting food for more than a day, consult your veterinarian right away.
Some causes of anorexia are mouth pain possibly from an abscessed tooth, kidney failure gastrointestinal disease, diseases of the liver, ulcers, feline infectious anemia, intestinal obstruction, a viral infection, and pancreatitis, Addison's disease ingestion of poison, feline infectious peritonitis, heartworm, some medications, and change in diet and common stress.
From time to time a cat will refuse to eat when a new person or animal is introduced to the family circle. Keep track of any out of the ordinary behavior your cat may be displaying along with the anorexia and give details those to your vet. If anorexia is combined with other symptoms such as vomiting, weight loss, diarrhea, drooling or lethargy, breathing difficulties; contact your veterinarian on the double.
Since anorexia has so many potential causes, your veterinarian may need to execute a multiplicity of tests for a diagnosis. Your veterinarian may necessitate a fecal exam to check for parasites, an oral exam to test for damaged teeth or a foreign body, abdominal and chest X-rays, blood counts and urinalysis, and a basic physical exam to verify for growths wounds, or masses. Treatment for severe anorexia will commence with IV fluids to help care for and prevent dehydration. Nutritional support may also be required through a feeding tube, hand-feeding or appetite stimulants. Depending on the source of the anorexia, your veterinarian may also administer antibiotics for a bacterial infection, or even surgery if your cat's condition has need of it. In some instances, a veterinarian may propose a feeding tube. Feeding tubes can be used to provide blended foods and medications to that feline. These tubes can be left in for extensive periods of time but will most assuredly need to be replaced every two to three months. Your veterinarian will give you detailed instructions on how to care for a cat using a feeding tube.
If your cat is turning down food because of a behavioral issue--after all physical issues have been ruled out--try warming his/her food to persuade her/him to eat. If you have of late introduced a new diet, try mixing it with the feline’s former food to help her/him make the change easier.
