Short answer

The decomposition time of a cat can vary depending on various factors such as environmental conditions, temperature, and presence of scavengers. However, on average, it can take around 6 to 12 months for a cat's body to fully decompose.


The decomposition process of a cat begins shortly after its death. Firstly, the process begins with autolysis, which is the breaking down of cells due to the release of digestive enzymes and lytic enzymes. These enzymes start to degrade the cat's tissues, causing the body to become soft and mushy. As this process progresses, bacteria start to multiply rapidly and invade the body, leading to putrefaction.

During putrefaction, the bacteria break down proteins, releasing foul-smelling gases such as ammonia, hydrogen sulfide, and methane. The cat's tissues liquefy due to the bacterial activity, resulting in the formation of a fluid known as "corpse soup." This fluid seeps into the ground or surrounding areas, contributing to the spread of the decomposition process.

As time goes on, the decomposition progresses to the advanced decay stage. At this point, the body's organs have decomposed significantly, and the remaining tissues further break down. The cat's skeleton may start to become visible as the remaining soft tissues continue to decompose. Eventually, only the bones, fur, and any non-biodegradable materials remain.

Overall, the decomposition of a cat follows a similar process to other animal decomposition. It starts with autolysis, followed by putrefaction and finally advanced decay. The speed and extent of decomposition can vary depending on factors such as temperature, humidity, and presence of scavengers, which can accelerate the process significantly.

Intresting facts

  • When a cat decomposes, it undergoes a natural process called necrobiotic digestion, where tissue breakdown occurs due to the activity of bacteria and other microorganisms.
  • The decomposition of a cat follows a particular pattern, starting with the breakdown of soft tissues such as muscles and organs, which occurs relatively rapidly.
  • As decomposition progresses, the body goes through different stages: fresh, bloated, active decay, advanced decay, and finally, dry remains.
  • During decomposition, gases are produced by the microorganisms, leading to bloating and the potentially explosive release of these gases if not properly managed.
  • The speed of decomposition can be influenced by various factors, including temperature, humidity, access to oxygen, insect activity, and the presence of scavengers.

Summary and final thoughts

The decomposition time of a cat can vary depending on different factors such as environmental conditions, burial depth, and presence of scavengers. Generally, the decomposition process of a cat starts with the initial stages of autolysis and putrefaction, wherein the enzymes within the body start to break down the tissues. This process can last for a few days up to several weeks. As the decomposition progresses, the body continues to decompose further, with the breakdown of both soft and hard tissues, eventually leaving behind only the bones. The complete decomposition of a cat can take several months, possibly up to a year or more, depending on the aforementioned factors.
