Whether as a stand-alone treat or combined with your favorite jam for a heavenly peanut butter and jelly sandwich, a spoonful of peanut butter can delight both our hearts and our taste buds. Recent studies show that in the United States alone, about 700 million pounds of delicious peanut butter is consumed yearly. Besides its yummy taste, peanut butter is also considered a superfood, packed with tons of vitamins, fiber, protein, and potassium! If you are a ferret owner, you may now be wondering - can ferrets eat peanut butter?

A common misconception that most pet- owners are guilty of is thinking that whatever is nutritious for us humans will also be beneficial for our pets.

Keep in mind that animals differ from humans when it comes to specific nutritional needs. While it is true that peanut butter can provide us with nutrients enough to energize us and keep us going for the entire day, these same nutritional content can cause serious health concerns for our ferrets.

With that being said, giving peanut butter to our little pets is a big no-no.

Keep on reading to find out why.

Why Can’t Ferrets Eat Peanut Butter?

To understand why ferrets are discouraged from indulging in this type of food, it is important to learn about their natural diet. For many years, ferrets have existed and survived in the wild by learning to find sustenance from whatever food they can hunt and feed on such as rats, rabbits, birds, and snakes.

In other words, ferrets' digestive system is fine-tuned to efficiently digest the kind of food they get accustomed to eating in the wild.

Unlike other regular carnivores that can eat both animals and plant matter, ferrets are obligate carnivores. This means that they need to eat meat coming from the animals they hunt, for them to acquire the necessary nutrients to survive. But what’s wrong with a little chunk of peanut butter?

  • Peanut butter is made from finely ground roasted peanuts. As mentioned earlier, it is an excellent source of protein. However, this is rendered useless since obligate carnivores can only absorb proteins coming from animal sources. Instead of being properly utilized, protein from plant sources like that which is found in peanut butter can interfere with a ferret’s digestive process.
  • Aside from its high protein content, there is also the presence of complex carbohydrates in the form of sugar, which ferrets are not equipped to digest. Ingestion of food that is high in salt and sugar can result in a ferret's disrupted digestive system, often exhibited in the form of diarrhea, and serious intestinal concerns including cancer.
  • Keep in mind that ferrets cannot digest vegetable and fruit matters. Peanut butter, especially the chunky type, may cause intestinal blockage and result in serious, even life-threatening complications.
  • Ingesting unprocessed food also increases your pet ferret’s risk of developing cancer.
  • With all these potential health risks and complications, its easy to understand why you shouldn’t feed your ferrets peanut butter. There are certain conditions when it may be necessary to allow your pets a taste of some peanut butter. An example would be when trying to mask the taste of some bitter medications. However, this is only done under special conditions and never try to use the chunky type.

What Other Treats are Good for Ferrets?

Although peanut butter may not be an ideal option for your little ferret, there are many other healthier treats you can offer your beloved pets! Just make sure to choose the healthiest and safest ones. After all, their health matters so it pays to be a little meticulous when it comes to your ferrets’ diet.

Keep in mind that while they can be picky during adulthood, the food habits they get to adopt while they are kits will most likely stay with them their entire life.

Below are some examples of healthy and ferret-appropriate treats you may give your little kits.

  • Kitten food (should be supplemented with fatty acids)
  • Food pellets (lamb or chicken)
  • Raw or cooked chicken meat
  • Cooked/boiled eggs
  • Lamb, turkey or chicken bites

Guidelines for Choosing Ferret Treats

While it’s true that ferrets, especially those who have lived in the wild are great hunters, they do have small mouths with very sensitive gums and oral tissues. For this reason, there are a few things you may need to keep in mind when choosing the best treats for your pets.

  • Choose treats that are soft with smooth and rounded edges to lessen the risk of mouth and gum injuries.
  • Have the treats pre-cut to small bite-sized pieces to avoid the possibility of choking.
  • Try to find treats in the market that are formulated to avoid hairball formation, or dissolve ones that already exist.
  • Any meat (whether cooked or raw) that you may choose to give your ferret should be fresh and no more than 5 days old from the time you get it from the market or store.


Peanut butter may indeed be a delicious superfood for humans, but not for your ferrets. Still, there's no need to fret because delicious options abound for your little rascals. As ferret owners, it's part of our responsibility to do the choosing for them. We just need to be well-guided in providing for them treats and food that are healthy, well-balanced and appropriate for their nutritional needs.​​​​​​
