Thiamine (Vitamin B1) Deficiency in Cats

thiamine deficiency in catsThiamine (also known as Vitamin B1) is a water-soluble vitamin. Thiamine plays an important role in numerous body functions including helping the body metabolise carbohydrates into energy and  maintaining a healthy heart and nervous system. Thiamine is found in whole grains, some fruits, and vegetables, meat, liver, bread, brewers yeast, legumes, and milk.

Thiamine deficiency is quite rare in cats and is most typically seen when a cat has been fed a diet containing large amounts of raw fish.

Causes of thiamine deficiency include:

  • When a cat  is fed a diet containing large amounts of raw fish. Raw fish contains the enzyme thiaminase,  which destroys thiamine. Cooking destroys thiaminase, thus protecting thiamine.

  • Sulphur Dioxide (220) is a preservative found in some brands of 'pet mince'. Sulphur dioxide inactivates thiamine. [1] Pet food manufacturers, therefore, must carefully monitor their products to ensure they contain adequate levels of thiamine for cats.

  • Thiamine is soluble in water and therefore can be lost if cooked in water. If you are to cook your cat's food in water, then use as little as possible.

  • High heats can also destroy thiamine. Once again, pet food manufacturers must carefully monitor their products to ensure they contain adequate levels of thiamine to compensate for the loss during the cooking process.

  • Cheap/generic brands of cat food may not monitor these levels as carefully as they should, therefore it is always wise to choose your pet foods carefully and feed a varied diet.


Thiamine is not stored in the body and therefore is quickly depleted if the cat is fed an inadequate diet or goes without food for any period of time. It is, therefore, important to ensure the diet contains adequate amounts of this vitamin.
