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.
Nicotine is a rapid acting toxin and, often, pets will show signs of poisoning within 1 hour of ingestion. Some types of nicotine gums also contain xylitol, a sweetener which is toxic to dogs. The acid in the stomach slows the absorption of nicotine so the administration of antacids (e.g., H2 blockers) is not recommended. Pets ingesting small amounts of nicotine often vomit spontaneously and may self-decontaminate.
