Can cats eat peanuts? That is the question that many cat owners ask themselves when they are deciding what to feed their pet.
Cats can eat peanuts, but there are some considerations about how safe it is for them to consume this type of nut.
For example, it’s important to know if your kitty has any allergies, and if so, does he or she have an allergy specifically towards peanuts?
Peanuts may also not be a healthy food for cats because they lack protein and fat content in comparison with other sources of animal protein like meat or fish.
In this blog post we will discuss this subject in more depth.

They are also hard to digest, and contain the wrong type of protein for your cat’s metabolism.

The Dangers Of Peanuts For Cats
On the other hand, there are plenty of reasons why you shouldn’t feed peanut butter to your feline friend:
1. High In Fat Content / Weight Gain
It’s very high in fat content for one thing – around 50% of its calories come from fat! That may not sound like much but if you were thinking about giving it as an occasional treat then think again because this could seriously affect your pet’s health. Cats have different dietary requirements than us so they need less fatty foods.
Obesity, in turn, causes diabetes in cats.
The symptoms of feline diabetes include:
- thirst
- increased urination
- weight loss
- increased appetite.
2. The Wrong Type Of Protein
Although peanuts are loaded with protein, it is the wrong type of protein for your cat’s metabolism.
Cats are obligate carnivores, which means their digestive systems are designed to break down proteins only obtained from animal sources.
Peanuts contain a high level of a form of protein called lectin which is harmful to your cat’s red blood cells and may cause vomiting, diarrhea or anemia.
It doesn’t contain the nutrients cats require to stay healthy and function properly, such as taurine, which can only be found in animal sources.
3. Hard For A Cat To Digest
Peanuts are very hard for cats to digest so this can lead to stomach upset.
4. Shells Are Dangerous
Peanut shells can become a choking hazard if swallowed by your cat.
When broken into pieces or chewed, the shells are extremely sharp. It can cause your cat to rip their stomach lining or vocal chords.
5. Salt Poisoning
Although cats do need salt as part of their diet to be able to function, too much salt can cause salt poisoning (hypernatremia).
This can result in an imbalance in the electrolytes and cause vomiting, diarrhea, lethargy, decreased appetite, and excessive thirst.
A small amount of salted peanuts such as one or two won’t harm your cat, but keep in mind that cats are little animals, and even a tiny amount of salty things may have an impact on their health.
Are cats allergic to peanuts?
Cats that are allergic to peanuts can have a very dangerous reaction because their immune system will go into overdrive.
This may result in anaphylactic shock, which is life-threatening and could potentially be fatal.
Although it’s not likely for your cat to experience the full range of symptoms associated with peanut allergies, here are some warning signs you should look out for according to WebMD (https://pets.webmd.com/cats/cat-allergy-symptoms-triggers#1):
- rashes or hives on his skin
- wheezing
- coughing sneezing or shortness of breath
- watery eyes itching around his nose and mouth
- vomiting
- diarrhea
- loss of appetite
- fatigue
- weakness
- seizures
- collapse
If you notice any of these symptoms after feeding your pet something containing peanuts then take him immediately to the vet as this could indicate an emergency situation!

We recommend to not give peanuts to your cat, but if you do, here is the correct way to do it:
Preparing Peanuts for Cats Safely

2. Remove the shells
It is extremely important to remove the shells from nuts before feeding them to your cat .
This is because the shells are very hard and difficult to digest. Â They can cause your cat’s stomach to get scratched or injured due to their sharp edges.

If you do decide to give peanuts to your cat, then one or two peanuts per week is more than enough.
Feeding anymore than this can start to put your cat in danger of salt poisoning, vomiting, and other health conditions.
