Is Feeding Your Cat Bacon Grease a Bad Idea?

Curious creatures, cats love to take a bite out of everything that their paw parents might be eating, and bacon or bacon grease is no exception.

When you slow-cook bacon on a stove or oven for hours, the rendered fat, which turns into a liquid form, is known as bacon grease. Once it solidifies, this grease can be used in cooking and frying various dishes. 

While bacon grease can be healthy for humans, it is terrible for cats.

Let’s take a look into why bacon grease is bad for cats.

Why is bacon grease bad for your cat?

Feeding Your Cat Bacon Grease

Cats require meat in their daily diet to fulfill their nutritional needs. Bacon grease added to your cat’s food can gravely affect your feline due to high salt, fat, and nitrate levels. It can cause your cat to become critically ill or even fatal. Let’s explore why these components pose dangers.


Felines need small amounts of sodium for better growth and development. Exposure to too much of this mineral could harm your cat. With only a 740 mg daily sodium requirement for adult cats, additional salty treats combined with the sodium already found in cat food would easily result in cats consuming more sodium than is safe. This can lead to Sodium Ion poisoning.

If you suspect Sodium Ion poisoning in your cat, look out for the following symptoms:

  • Diarrhea
  • Vomiting
  • Lethargy
  • Dehydration
  • Convulsions

While cooked, unseasoned bacon can be occasionally fed to your kitty in small portions; it is best to avoid bacon grease entirely.



An adult cat needs only up to 5g of fat daily and can get extremely ill if consumed beyond that. The fat in bacon grease can trigger inflammation in the pancreas and cause pancreatitis, affecting other organs. This can lead to serious illnesses and be lethal if left untreated.

Watch out for these symptoms, and seek medical care if your cat exhibits any of the following:

  • Fever
  • Vomiting
  • Dehydration
  • Lethargy
  • Low appetite
  • Bloated belly
  • High heart rate
  • Yellowish eyes or skin

Stay in touch with a vet and rush to the clinic as soon as you notice these symptoms. 


Bacon grease may also have nitrates, which can be toxic for your kitty. Nitrite poisoning occurs due to high ammonia levels in the bloodstream, which can be fatal if not treated promptly. It can lead to:

  • Weakness
  • Ataxia

Immediately visit your kitty’s vet if you believe it has consumed bacon grease and is suffering from Nitrite poisoning.

Avoid feeding your cat bacon or bacon grease to protect them from fatal illnesses. If you feel tempted to give treats to your fur baby, opt for something safer.

If you have questions about which foods or vegetables you can feed your cat, download PetMyPal and consult a licensed vet online. However, in cases of emergency or if you observe any of the symptoms mentioned in this article, rush to the clinic immediately.
