Cats eat spiders; kittens eat spiders – this is a fact most cat owners need to face. While there’s no need to panic if your cat eats a spider, it’s essential to understand what might happen if they do.

How Dangerous Can Spiders Possibly Be?

We all know that spiders can be dangerous. They can cause serious health problems in humans and even death in some cases. But how dangerous can they be to our feline friends? In truth, it’s not as difficult as you might think when you see your cats eating spiders. In most cases, cats can eat a spider without any issues, except for the black widow or brown recluse.

For this reason, owners of cats should take care when placing them near a potentially infested area, such as the garage or shed. The more significant thing to be concerned with is a spider bite. If a spider has bitten your cat, its local skin cells may be affected. Cat’s skin will react more to a black widow bite than other spider bites. Black widow spiders are among the most dangerous to cats.

Possible Allergic responses

If a cat consumes spiders or is the victim of a spider bite, hypersensitivity reactions may result. The symptoms of ingestion will typically present as gastrointestinal distress. However, if a spider has bitten your cat, you should generally keep an eye out for the following signs which could indicate poisonous spider bites:

  • bite wound, which is frequently physically uncomfortable,
  • allergic reactions,
  • cutaneous inflammatory disease,
  • a rosy hue to the skin,
  • difficulty breathing,
  • irritation of the skin,
  • severe irritation
  • a warm or hot sensation when touched,
  • Bruising,
  • anaphylactic shock
  • cutaneous necrosis
  • secondary bacterial infections

Final Thoughts

It’s important to note that the types of internal parasites that the insect carries may exacerbate the signs of cat-eating spiders. Some spiders may carry harmful parasites like the stomach worm Physaloptera. These worms may occasionally be transmitted to your cat. The problem may worsen if a cat consumes spiders tainted with pesticide and insecticide poisons. And, of course, if you have any concerns or it’s clear your cat was bitten by a spider, be sure to consult with your vet, who will provide veterinary advice, or take your cat to the nearest animal hospital to be inspected.
