Cat gastrointestinal tract

If your cat consumes peanut butter very often, or it eats large amounts all at once, it might develop digestive problems. These digestive issues can either be elementary, while at times, they can be severe. Here are some of the signs of a gastrointestinal problem:

If your cat has an allergic reaction to peanut butter, such as diarrhea, for example, avoid giving it any human antibiotics or other allergy medications, because they are toxic to cats. Call a veterinarian for medical advice, or stop providing your cat with food for the next 8 to 12 hours. You can also give your cat probiotics that were proven to help with diarrhea in cats.

Since cats already get all they need from their diets, which are based on meat and fish, excessive amounts of calories would pose a problem more than a health benefit. If your cat is one of the cats who are already chubby or struggle with weight, peanut butter is something you should avoid giving to your cat.

16 g of fats. Since it is manufactured using trans fatty acids to help store longer on a shelf, this causes a health issue to your cat, because those fats are hazardous and are considered as a significant toxic food substance.

In addition to that, make sure your cat always has access to fresh and clean water in sufficient quantities; in case it needs help to wash the peanut butter down its throat.

Peanut butter and aflatoxins:

Precautions concerning peanut butter and cats:

Sugar replacements: Xylitol

Over the last years, people have become more cautious about sugar levels, and there was a new health craze concerning anti-sugar diets. Many people started following No-sugar diets, or avoiding all foods with artificial sweeteners; as a consequence, many food companies opted for sugar replacement in their products.

This replacement is called Xylitol. Many brands that produce peanut butter adopted the same thing and started using Xylitol in their products instead of sugar, which is considered a negative aspect to your cats.

Xylitol is extremely toxic and lethal to animals, cats included. This led to several tragedies of pet parents losing their cats, dogs, or other animals, due to poisoning, because they did not know those brands were replacing sugar in their products with Xylitol.

In case you decide to give your cat peanut butter treats, make sure you check the ingredients of that brand and avoid products that contain Xylitol entirely. Here are some of the peanut butter brands which do not contain Xylitol in their formula:

  • Go Nuts, Go
  • Krush Nutrition
  • Nuts Nutrition
  • Nuts ‘N More
  • P 28 Foods
  • Protein Plus PB

You should be careful concerning other foods as well. Peanut butter brands were not the only ones who substituted sugar with Xylitol, so make sure you check the ingredients on the label before serving any kind of food for your cat.

Excessive sugar intake:

Many foods contain excessive amounts of sugar, and so dome some peanut butter brands. Too much sugar can encourage some cat diseases, and even lead or invoke other health conditions such as diabetes, obesity, premature aging, inflammatory changes in your cat’s body.

Some infections are encouraged by high sugar intake:

  • Yeast infection
  • Bacterial infection
  • Parasites

Too sweet is bad, and so is salty!

High sodium levels in your cat’s food cat evoke many health issues in your little paw friend’s body. It is best to search for unsalted peanut butter brands when it comes to your cat’s diet, it can be a bit challenging to find, but "better safe than sorry".
