How Long After a Cat Dies Does It Smell, and Is It Harmful?
The time it takes for a deceased cat to start emitting an odor is significantly influenced by the ambient temperature. In high temperatures, around 30 degrees Celsius (86 degrees Fahrenheit), the smell can begin within approximately three hours. Conversely, in cooler winter temperatures, the odor may not be noticeable until a day or two later. This rapid decomposition occurs because, after death, bacteria proliferate exponentially, causing the distinctive and potent smell of decay. This odor, primarily from decomposing tissue, can be detrimental to human health and requires prompt handling. Specifically, when a cat dies, its body begins to decompose, releasing gases such as ammonia and hydrogen sulfide. These gases are not only unpleasant but can also be harmful if inhaled in significant quantities. The absence of an active immune system post-mortem allows bacterial growth to accelerate, with the most rapid increase occurring within about two hours after death. Therefore, prompt and ap...
