Putting out cat food is something all cat owners can relate to. Yet, it is the stench of cat food that can be off-putting for those who don’t like the odor spreading everywhere. While cat food smell isn’t pleasing, it’s something that will be part and parcel of raising a cat. This is why you may ask, why does cat food smell so bad?
Cat food tends to smell bad because of its artificial flavor and raw ingredients. The smell of these ingredients is appealing to the cat but not as much to a human nose.
In the end, the idea is to make sure the cat wants to eat its food and that means tolerating the cat food smell.
Key factors include:
- Artificial Flavors
- Raw Ingredients
It’s also important to note you are going to be leaving the cat food out in the open. If it is wet cat food, there is going to be a certain stench that will start to develop if the food isn’t fully consumed.
This is why you should only be giving the cat food when it wants it. Otherwise, the food will get ruined and/or have a terrible smell that spreads throughout the area.

It all starts with the raw ingredients.
When asking “Why does cat food smell so bad?” you will have to look at the formulation itself. When the ingredients are put into a recipe such as this, they are going to be as raw as possible.

2. Artificial Flavors
When asking “Why does cat food smell so bad?” you should also look at the flavoring that is used to spice up the food.

It’s important to note when they use these artificial flavors, they are more focused on what a cat likes eating rather than what you want to smell.
The goal is to attract the cat and those are the flavors they add to the mixture.
This is key because it will often impact how the cat food smells whether it is dry or wet.

3. Exposure to AIr
