Eggs – While cooked eggs are high in protein and make an excellent treat, raw egg whites contain a protein called avidin, which can deplete your cat of biotin, one of the B vitamins (Biotin is essential to your cat’s growth and coat care). Symptoms of biotin-depletion include:
- hair loss
- growth retardation
If your cat is showing these symptoms, the situation is critical, and she should be taken to the veterinarian.
Fish – There is an enzyme in raw fish called thiaminase that destroys thiamin, or vitamin B1. Thiamin is essential to a cat’s well-being; the lack of it can lead to neurological disorders. Symptoms of thiamin deficiency are mostly neurological. These include:
- loss of weight and appetite
- wobbly or uncoordinated movements
If left untreated, thiamin deficiency can lead to convulsions and coma. This is an urgent situation; if you notice these symptoms in your cat, take her to the veterinarian as soon as possible.
