I have to say that lecithin is very good for cat hair, especially feeding lecithin to cats has obvious effect on cat hair loss. When cats lack this nutrition, they will lose their hair and dry up. Lecithin for cats can supplement this. Generally speaking, there are no other skin diseases. Eating lecithin for a month or so for cats like Visa will reduce hair loss and beautify, so feed lecithin regularly for a long time.
