Folate is essential for DNA synthesis and cell division, making it particularly important during periods of rapid growth such as kittenhood and pregnancy. It works closely with vitamin B12 to produce healthy red blood cells, and a deficiency in either vitamin can cause a specific type of anemia where red blood cells are abnormally large (megaloblastic anemia). In pregnant queens, adequate folate supports proper fetal development and helps prevent birth defects. Folate is found in organ meats, eggs, and some green vegetables, and is well supplied by commercial cat foods.
A small portion of chicken liver (about 15g) provides roughly 100–150mcg of folate — your adult cat needs approximately 50–200mcg per day, similar to the folate content in a cooked egg. Commercial cat foods provide adequate folate, and supplementation is rarely needed.
0.0% of daily nutrient intake
Vitamin B9 (Folate) makes up 0.0% of your cat's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Megaloblastic anemia (large, immature red blood cells), poor growth in kittens, weight loss, lethargy, and increased susceptibility to infections. In pregnant queens, deficiency may contribute to fetal developmental problems.
Folate is water-soluble and excess is readily excreted. Toxicity from dietary sources is not a concern for cats.
| Life Stage | Size | Min | Max | Unit | Notes |
|---|---|---|---|---|---|
| Adult | — | 50 | 200 | mcg | Folate requirements are well met by meat-based diets. Higher needs during pregnancy and lactation. |
| Pregnant / Nursing | — | 100 | 400 | mcg | Pregnant queens need significantly more folate for fetal cell division and development. Quality kitten food or pregnancy diets provide elevated levels. |

B vitamins work as a team in metabolic pathways. Biotin and folate both serve as coenzymes in critical metabolic reactions, and adequate levels of all B vitamins ensure optimal energy metabolism and cell function.
What this means: Feed a varied meat-based diet that naturally provides the full spectrum of B vitamins. Eggs, poultry, and fish together cover all B vitamin needs without the need for individual supplementation.
