To “let the cat out of the bag” is a colloquial phrase that means to tell some facts that were perhaps a secret beforehand. It can be positive or negative information, and it can be used whether or not you accidentally told the information, or did it on purpose.
Origin Of The Phrase “Let The Cat Out Of The Bag”
There are a few theories as to the origins of the phrase “let the cat out of the bag.” The first is that, in the middle ages, sellers would swindle customers by placing a cat in a bag instead of a pig. When the buyer got home, they would let the cat out, and see they had been tricked. However, this theory doesn’t hold much weight. There would be a big weight difference between a cat and a pig, and getting a cat, or a pig for that matter, into a bag might not be an easy task depending on the temperament of the animal.
Another theory is that the word cat refers to a type of whip used in nautical punishments called a cat-o-nine tails. This whip was kept in a red bag, and it may have been said that the sailor who revealed the crime of another was “letting the cat out of the bag.”
The most likely theory is that if you imagine it, it would simply be impossible to get a cat back into a bag once you let it out, much in the same way that it is impossible to put a secret back once it is let out.
The first published written usage of this phrase was in 1760. It appeared in a book review in the London Magazine. However, it was also used in a letter from Johannes Agricola to Martin Luther during the Protestant Reformation in 1530.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
