Peanut butter contains relatively small amounts of sugar. You need not worry much if your feline friend is suffering from diabetes. You can still give her an occasional treat of peanut butter once in a while.

However, just to be certain, it is good to first, counter-check the ingredient of the peanut butter brand you have and also consult with your vet if it is okay to give your cat peanut butter if they are diabetic.

What should I do if my cat suffers from diarrhea after eating peanut butter?

Did you know that cats just like humans may also be allergic to peanut butter?

So then, what should you do in case your pet suffers from bouts of diarrhea after eating peanut butter?

You need to take your cat to the vet. There are brands of peanut butter that contain xylitol, which is a health hazard to your feline friend.

You also need to avoid giving your cat anything in the next 8 – 12 hours except for water. When your cat is experiencing diarrhea, he loses a lot of body fluid thus becomes quite dehydrated. You need to give your cat plenty of water to keep him hydrated and his blood sugar levels up.

The symptoms can naturally wear off after a few hours so there is no need to panic and be all stressed up.

However, if the symptoms persist, you need to seek medical advice from your vet on how best to treat your feline friend depending on the conditions.

Are Cats Allergic to Peanut Butter?

As briefly highlighted earlier, peanut butter is not toxic for your cat, however, there are cats that can be allergic to it.

Experts recommend that peanut butter is not a very healthy food to feed your cat on a regular basis. You need to give your cat peanut butter in moderation.

You can opt to stick to natural sources of animal protein like fish and meat because cats are carnivores anyway and would get healthy proteins from the same. Peanut butter can be used as a treat or reward to encourage good behavior.

Is Peanut Butter Bad For Cats?

Some cats may even develop undesirable begging habits when they see you holding a jar of peanut butter. Trust me, the last thing you want is your feline friend being melodramatic and embarrass you in front of your guests just because you denied them a scoop of their favorite treat.can cats eat peanut butter guide

Avoid giving your cat peanut butter on a regular basis because there are cats that will develop a bad habit of showing disinterest in their own usual meals. This can be a very unhealthy trend because peanut butter should only be treated as a rare snack and not a meal substitute.

Train your cat to only get used to little occasional treats of peanut butter. There are places where people use peanut butter in pest control to lure insects and mice.

Some pet owners mix peanut butter and say something like cheese and place it in a mouse trap. This can be hazardous for your cat if she stumbles upon this death trap.

Can Kittens Eat Peanut Butter?

I know it can be very excruciating to see those adorable eyes of your kitty staring at your jar of peanut butter. So you are probably asking whether it is okay to give your kitten peanut butter.

Kittens do not have a fully formed immunity system. When giving your kitten peanut butter for the first time, you simply have no clue as to whether they are allergic to peanut butter or not.

Simply take a tiny bit of peanut butter on your finger and just let her lick it. Watch to see how she reacts.

Observe your kitten over the next few hours. If she will pose any allergic symptoms then you will know that your feline friend is allergic to peanut butter.

Symptoms of allergy include the following:

  • Vomiting
  • Diarrhea
  • Severe dehydration
  • Uneasiness/ restlessness
  • Gastro-intestinal upsets

Once you notice that your kitten is showing such symptoms, you need to stop giving her any more peanut butter lest you make things worse for the poor kitten.

Naturally, the allergic symptoms could wear off by themselves after a couple of hours.

If your kitten is still vomiting and experiencing bouts of diarrhea, you need to rush her to the vet or if the vet can come visit her at home the better for you. Stop giving her more peanut butter if she has poor tolerance for it.

Peanut butter can also be harmful to your kitten as it can easily get stuck in her mouth and throat. That is why I would over-emphasise on the amount of peanut butter that you give your cat.

It is not entirely harmful to treat your kitty to a one-time treat of peanut butter because who likes to eat the same boring food every day! A little change once-in a while is good but don’t overdo it.

In a nutshell, your cat can eat peanut butter, once in a while. You can give her as an occasional treat and not as a meal replacement.

Remember that there are cats that may be allergic to some peanut butter ingredients. There are also some brands of peanut butter that contain xylitol, which is harmful to your feline friend’s health.

The most common side effects of too much peanut butter include, diarrhea, vomiting, obesity, indigestion and it can also get stuck in your cat’s throat.

This may not be uncommon for cats because their digestion system is not the same as ours but, you need to be aware that indigestion can be a serious issue for cats when they eat human food.

Felines may not be able to digest peanuts as well as we humans can as it can easily give them a stomach upset.

There are two sides to every coin, even though peanut butter may have side effects on some pets, it is also a rich source of unsaturated fats that are considered healthy. This may be useful and prevent your cat from suffering from heart disease.
