Should cats eat soy?
Soy is often added to cat food under the guise of protein. This cheap switch in diety protein makes for a very dangerous ingredient. Feeding is not jusy misguides, it can cause some rather serious problems in cats.
- It disrupts endocrine function and increases thyroxine (T4) levels in cats. An elevated T4 level can indicate hyperthyroidism.
- It can cause digestive upset, including flatulence.
- By interfering with protein digestion, trypsin inhibitors have caused stunted growth and pancreatic problems in test animals.
- Phytic acids contained in soy inhibit the body’s absorption of calcium and other minerals.
- It’s unknown how the phytoestrogens in soy affect cats but, given that soy isn’t a natural part of a cat’s diet, it’s more likely to have a negative than a positive effect.

The thyroid hormones, thyroxine and triiodothyronine, are tyrosine-based hormones produced by the thyroid gland which are primarily responsible for regulation of metabolism.
Hyperthyroidism – Wikipedia
Hyperthyroidism, often referred to as an ‘overactive thyroid’, is when the thyroid gland produces and secretes excessive amounts of the free – not protein bound and circulating in the blood – thyroid hormones, triiodothyronine and/or thyroxine.
Trypsin inhibitors – Wikipedia
Trypsin inhibitors are chemicals that reduce the availability of biologically active trypsin, an enzyme essential to nutrition of many animals, including humans.
Phytic acids – Wikipedia
It is the principal storage form of phosphorus in many plant tissues, especially bran and seeds.
phytoestrogens – Wikipedia
Phytoestrogens are plant-derived xenoestrogens (Xenoestrogens are a type of xenohormone that imitates estrogen).
