2) 5 Steps To Safely Feed Peanut Butter To A Hamster:

Knowing how to feed peanut butter to a hamster will make it easy for your pet to enjoy eating it. Besides, it will ensure you do not overstep and risk your pet’s health by serving them the wrong way.

If you’re wondering how peanut butter can harm your pet, here is how. Serving a large chunk of peanut butter to your pet will increase the chances of it getting the creamy structure stuck in the inside of your pet’s mouth.

To avoid you and your pet from all this trouble, here are the steps that you need to take:

  • Take the peanut butter out of the refrigerator. Grab a spoon and only get the recommended amount for your pet hamster.
  • Let it sit for a couple of hours so that it is not cold when you serve it. Hamsters tend to run away from cold peanut butter so letting it sit outside the refrigerator will get it to the desired temperatures.
  • Take a small amount of peanut butter using a teaspoon and smear it to a hard surface. You can either use a small piece of food for this or simply on the edge of your pet’s food bowl.
  • Let your pet have a go at it. Your pet will likely not eat all of it at once and he or she will taste some then runaway, and then later come back for more.
  • When your pet is done eating, you should remove the leftovers.

Since your pet will be licking it from the wood or the edge of the food bowl, you will not have to worry about it getting stuck to the insides of your pet’s mouth.

Additionally, it will also prevent your pet’s cheeks from getting stuck together. Yes, you read correctly! Large blobs or chunks of peanut butter can make your little one’s cheeks get stuck together.

Bonus Treat:

To mix things up for your little one, you can make homemade treats with peanut butter. All you need is a cup of whole wheat flour, with ½ cup of oats, and 1/3 cup of plain peanut butter.

Add an egg, some water, and mix the ingredients thoroughly. When the mixture is prepared, make circular treats for your little one. You can also make a square, triangle-shaped, or whatever shape you like.

Place it in a preheated oven and let it sit in at 180 degrees for 15 – 20 minutes. Serve and let your pet have a feast! But, make sure you don’t overfeed or serve them frequently.

Risks Of Feeding Peanut Butter To Hamsters

Anything that is fed in excess amounts can turn out to be bad for your pet hamster. Here are some possible risks and dangers that are involved with feeding peanut butter to your dear friend.

1) Aflatoxin Poisoning:

Peanuts usually tend to mold with the passage of time. Unfortunately, they mold at a higher rate and can have two common types of molds. These include:

  • Aspergillus parasiticus
  • Aspergillus flavus

Both of these produce aflatoxins when they’re molding and are exposed to light and air. These can end up being fatal to your pet friend.

So, if you have made peanut butter or got store-bought with molded peanuts, there is a good chance that your peanut butter has aflatoxins.

The only way to avoid the risks of exposing your pet to aflatoxins is to make peanut butter at home with fresh peanuts. This way, you will have control over the peanuts and oils that you are adding to the peanut butter.

2) Cheek Pouch Clogging:

Peanut butter has a creamy texture. But the creamy texture is sticky and can easily stick to the cheek pouches of your little one. This is referred to as cheek pouch clogging and can put your pet in severe discomfort.

Not only does it cause discomfort but it also decays with the passage of time. As a result of this decay, it will lead to infections in the cheeks and insides of your pet’s mouth.

In that case, you will have to take your pet to the local veterinarian immediately. He/she will likely suggest antibiotics and will have to clean the cheeks via a procedure.

3) Digestive Complications:

Your little one is known to have a sensitive digestive system and it is common in all hamsters. When you first introduce your pet to new foods, he or she will likely suffer from digestive complications.

Obesity will open up the pathways to a number of other health complications including heart and joint issues. Due to this, you need to control the serving size of your pet hamster.

5) Pro-Inflammatory Effects:

Hamsters already have a hard time suffering from severe inflammatory conditions. This includes arthritis that hamsters are more prone to. Peanut butter contains a high concentration of lectin.
