Cats and Crab, What You Need to Know

The crab is a type of arthropod with a thick exoskeleton best known for its pincers and sideways walking movement. Being a crustacean, crabs are part of a large group of invertebrate animals that includes lobsters, shrimp, and crayfish (or crawdads as we called them growing up).

As crabs are usually found in or by the sea, and cats hate water, it’s pretty uncommon that cats would come into contact with a live crab. However, as the following video shows, chance encounters do happen:

Since cats are predators, it’s not surprising to see the cat going after the crab. Cats are also obligate carnivores, so meat is the only food cats really need to eat and they derive little to no nutrition from plants and vegetables.

But, is crab a good source of meat for cats? Would they like it?

From a nutritional standpoint, crab isn’t a bad food. One hundred grams of Alaskan king crab contains about 97 Calories, 19.4 grams of protein, and significant amounts of vitamin B12, zinc, copper, and selenium.

Can Cats Eat Crab?

While cooked crab is generally okay to give cats, fresh crab carries some risks of sickness from bacteria and parasites.

It’s unlikely your cat would get sick from eating raw crab, but why take chances with their health? Instead, just stick with providing them with the occasional cooked crab as a treat.

Here’s a cat that didn’t wait for their dinner to be cooked. It shows that there’s another danger to eating crab that’s TOO raw…

Can Kittens Eat Crab?

Because of their immature immune and digestive systems, kittens are susceptible to illness. Bacteria and parasites that could be in raw crab are even more likely to make a kitten sick than an adult cat.

Make sure any crab you feed your kitten is cooked first, and doesn’t contain any additives like salt or spices. Even then, it should be given only as on occasional treat and in small quantities.

High-quality, grain-free kitten food has all the nutrients a growing kitten needs. So, it’s best to stick with something like Wellness kitten food or else Taste of the Wild kitten food.

Benefits and Drawbacks to Cats Eating Crab

As we have learned, cooked crab can provide protein that is required in your cat’s diet. However, fresh crab, contaminated with a bacteria known as Vibrio, has been identified as a source of human illness.

Vibrio usually only affects people with compromised immune systems. Most commonly associated with eating raw oysters, the bacteria normally causes gastrointestinal symptoms, but in serious cases has resulted in the loss of limbs and even death.

While cats are not known to be affected by Vibrio, it’s best to be safe and only give your cat cooked crab.

Additionally, heavy metals, such as cadmium can become concentrated in crab meat. Cats are particularly sensitive to some types of heavy metal poisoning, so it’s best to limit the amount of crab you give to your cat.

Perhaps most importantly, crab are a known source of food allergy in humans and might also be for cats. Food allergies are the third most common type of feline allergy, surpassed by only flea bite allergies and sensitivity to inhaled substances.

In cats, food allergies usually manifest themselves as skin reactions. Symptoms of food allergies in cats can include:

  • Sneezing, snoring, coughing, and wheezing
  • Itchy skin, scratching, and chewing
  • Ear infections
  • Runny eyes
  • Vomiting
  • Diarrhea
  • Swollen paws
  • Possible farting

If you do decide to give your cat crab, make sure you stay alert for any of the above symptoms.

Healthy Alternatives to Crab

Adult cats are fine to have a little bit of cooked crab from time to time. With all of the great options out there, why not try a seafood-themed cat food? There are also seafood cat treats that can satisfy your cat’s craving for crab.

There’s no rush to feed crab to your cat, however. They don’t need it to survive, so any high-quality, meat-based cat food will be great for them, such as Wellness or Taste of the Wild cat foods.

So, can cats eat crab?
