Feline Vitamin Deficiency Syndromes
Of the vitamins cats need, some are made by the body, some from food. Lack of a specific vitamin causes a specific deficiency syndrome; long ignored, it can be fatal.
Signs of Vitamin Deficiency in Dogs
Vitamins work together for dog health. Deficiency shows observable changes. Here are the signs of vitamin deficiency in dogs.
What Terrible Consequences Come from Cat Vitamin Deficiency?
High-quality cat food rarely causes malnutrition, but vitamins don't keep well so content is low; supplement moderately. Our team explains the consequences of deficiency.
Vitamin B Deficiency and Toxicity in Cats
Cats need B vitamins, but the margin matters: too little brings dry coat, weakness, and spasms, while too much — usually from loading up on liver or human supplements — causes gum disease, stiff neck, poor bone growth, and dull coat. Skip human vitamins and liver-heavy diets; if toxicity appears, cut the source and rebalance with vet-guided fluids and calcium.
Rabbit Vitamin A Deficiency
Vitamin A keeps rabbit mucous membranes intact and vision sharp; deficiency, worst in winter and early spring, brings slow growth, weak coat, nerve signs, eye damage (conjunctivitis, keratitis, even ulceration), and in pregnant does premature birth or dead malformed kits. It stems from low-carotene feed, poor gut or liver absorption, or vitamin loss in storage. Diagnose by history, lesions, and plasma vitamin A below 0.2 to 0.3 mg/ml.
Niacin (Vitamin B3) Deficiency in Dogs and Cats
Niacin (vitamin B3) deficiency in dogs and cats causes pellagra-like signs, oral and esophageal ulcers, black tongue in dogs, diarrhea, anemia, and symmetric dermatitis. It follows corn-heavy diets low in tryptophan, and is corrected with dietary niacin.
Biotin (Vitamin H) Deficiency in Dogs and Cats
Biotin (vitamin H) deficiency in dogs and cats causes scaly dermatitis, hair loss, poor growth, and later weakness, diarrhea, and hind-limb paralysis. It is usually due to raw-egg white (avidin) or gut flora imbalance, and is corrected with dietary biotin.
Vitamin K Deficiency in Dogs and Cats
Vitamin K deficiency in dogs and cats impairs clotting-factor synthesis, causing prolonged bleeding time, subcutaneous and body-cavity hemorrhage, and anemia. It arises from malabsorption, long-term antibiotics, or certain poisons, and is treated with vitamin K and management of the underlying cause.
Vitamin E Deficiency in Dogs and Cats
Vitamin E deficiency in dogs and cats, often with selenium lack, causes skeletal muscle degeneration, reproductive failure, and in cats cerebellar ataxia, plus a fat-tissue inflammation known as yellow fat disease. It is corrected with dietary vitamin E and treatment of any gut disease.
Vitamin D Deficiency in Dogs and Cats
Vitamin D deficiency in dogs and cats impairs calcium and phosphorus use, leading to rickets in the young and osteomalacia in adults, with bone pain, lameness, and deformities. It is prevented and treated by correcting diet, ensuring sunlight, and veterinary-directed vitamin D and calcium.
