Now I'm confused. I'm sure it's excretion, not egestion. Isn't egestion the removal of unwanted food substances from the body?

not quite. some insects eliminate uric acid crystals through their intestine. Almost all insects actually... This is because of some structures named Malpighi tubes.
And there are other exceptions like that.
But generally, you got it.

Feces is the excretion of undigested food from the digestive tract.

Urine is the excretion of metabolic waste from the urine tract (which recieved the waste from the cardiovascular system).

Egestion - from GI tract, waste of digestion
Excretion - other than digestive system

Ammonia is toxic and must be turned to urea by combining with CO2!
