In 2009, an estimated 62.1 million metric tons of eggs were produced worldwide from a total laying flock of approximately 6.4 billion hens. There are issues of regional variation in demand and expectation, as well as current debates concerning methods of mass production.
Olives are not toxic to cats, but have little nutritional value. Green olives and pimentos contain chemicals similar to those found in catnip, so some cats may be especially excited by olives.
/ 0. i wouldn't feed them olives with the pit still inside and please keep in mind that canned or jarred olives are very high in salt, which isn't very good for dogs. The oil, while not literally toxic, can be too rich for some dogs. So I'd say use exceedingly sparingly if you are planning to use the oil or feed olives.
