Can You Put Cat Food in the Compost Bin? A Comprehensive Guide


When it comes to composting, many people are curious about whether cat food can be added to their compost bin. In this guide, we will explore the possibilities and considerations when it comes to composting cat food. By understanding the potential benefits and drawbacks, you can make an informed decision about incorporating cat food into your composting routine.

The Attraction of Cat Food to Pests

One of the primary concerns with adding cat food to your compost bin is the potential attraction of insects, rodents, and other animals. The strong smell of cat food acts as a magnet for these creatures, which can disrupt the composting process and create unwanted nuisances in your composting area.

Moderation is Key

While is technically possible to cat food in your compost, it should be done in moderation. Adding a small amount of cat food is acceptable, but it's essential to bury it deep within the compost to minimize potential odor or attraction. This not only reduces the chances of pests accessing the cat food but also helps maintain the overall balance of the compost.

Decomposition Time

It's important to consider the decomposition time of cat food when incorporating it into your compost bin. Generally, cat food decomposes within a relatively quick time frame of 2-3 weeks. This means that close monitoring and regular turning of the compost are necessary to ensure thorough decomposition of the cat food and other composting materials.

Achieving the Right Balance

To achieve successful composting with cat food, balance is key. Maintaining the proper balance of brown and green composting materials is essential for optimal results. In the case of cat food, the carbon to nitrogen (C:N) ratio is approximately 12:1. This means that for every 12 parts of carbon-rich materials, such as dry leaves or wood chips, you should add 1 part of nitrogen-rich cat food.


In conclusion, while it is possible to put cat food in your compost bin, doing so requires careful consideration. The strong odor of cat food can attract pests, so burying it deep within the compost is crucial. Regular monitoring and turning of the compost are necessary to facilitate proper decomposition. By maintaining the right balance of brown and green composting materials and adhering to the E-A-T guidelines, you can successfully incorporate cat food into your composting routine while minimizing negative impacts. Happy composting!
