Many pet owners worry about the safety of their furry friends, especially when it comes to unusual risks like tarantula bites. It’s a valid concern—tarantulas are venomous, and their reactions with small animals can be unpredictable.

Our blog post dives into this topic, offering insights on how tarantula encounters could affect your cat or dog and what you can do to prevent danger. Keep reading; we’re uncovering some crucial tips for keeping your whiskered pal safe from eight-legged threats.

Understanding Tarantula’s Venom

Diving into the world of tarantulas, we uncover the nature of their venom—an intricate concoction with varying effects on our feline friends. While typically not lethal, it’s crucial to grasp its potential impact on cats and even dogs, ensuring pet owners are equipped with knowledge to safeguard their beloved companions.

Potential Effects on Cats

Tarantula venom is not a joke for cats. It might make them feel sharp pain and their skin can swell up. Cats might also throw up, have diarrhea, or shake like they are cold. In bad cases, the poison can hurt their whole body.

If your cat gets bit by an Old World tarantula, it could be really dangerous. Some spiders’ bites are strong enough to put your pet’s life at risk. Watch your cat close if you think it got bit by a tarantula, and get ready to rush to the vet if needed.

Next, let’s see if a tarantula can actually kill a dog.

Potential Effects on Dogs

Dogs may react differently to tarantula bites compared to cats. Their size and fur can protect them more. But, if a dog gets bitten, it could still get hurt or feel sick. Big dogs might only have a small pain spot where the bite is.

Little dogs could get more sick because they are smaller.

If your dog acts strange after meeting a tarantula, take them to the vet fast. Look for signs like swelling, pain, or not wanting to eat. Always check your yard for spiders if your dog likes to dig and chase things – you want them safe from danger.

Next, let’s see if these eight-legged creatures pose a real threat of death to our feline friends.

Can a Tarantula Kill a Cat?

While it might sound like the stuff of nightmares, let’s shed some light on the stark reality—yes, a tarantula has the potential to pose a serious threat to your feline friend. The question isn’t just about whether a spider can bite, but rather what happens when those venom-laden fangs meet curious kitty whiskers.

Tarantula Attack on Cats

A tarantula attack on cats can be scary. These spiders have venom, but it’s not made to kill cats. Usually, a cat will be okay after getting bit. The spider might cause some pain and swelling where it bit the cat though.

If your cat messes with a tarantula, watch for weird signs like throwing up or quick changes in poop habits. Some types of tarantulas are really dangerous to pets. For example, the C.lividus spider can hurt them a lot. If you see your kitty acting strange after playing with a spider, get help from an animal doctor right away.

Symptoms to Look Out for After a Cat’s Encounter with a Tarantula

If your cat meets a tarantula, it might get hurt. Watch your cat closely for any changes in how it acts or feels.


  • Look for redness and swelling where the spider may have bitten your pet. This sign tells you the area is hurt.
  • Your cat might act very upset or strange, which can lead to other health problems.
  • Drooling can happen if your cat has touched or hurt a tarantula with its mouth. It’s their body reacting to something bad.
  • Pawing at its face or eyes is a clue that something is bothering your cat’s eyes or mouth.
  • Eyes that are watery or full of gunk can mean your cat got tarantula hairs in them, which hurts and irritates.
  • Vomiting is not normal for cats and can be a sign that the spider’s poison is making them sick.
  • Big changes in how they behave, like not wanting to play or hide more than usual, may show they are in pain.


What If a Cat Eats a Tarantula?

Curiosity can sometimes lead a cat to snack on something quite unusual — like a tarantula. While the thought might trigger alarm, understanding the risks and remedies becomes crucial for feline guardians when these eight-legged creatures become an unintended treat.

Possible Health Risks

If a cat eats a tarantula, the hairs can hurt its mouth. This may make the cat drool and not want to eat. Cats’ bellies might get upset if they swallow these hairs. Vomiting or diarrhea could happen from this irritation.

Cats are tough, but tarantula venom could still be bad for them. The poison might not kill cats, but it can make them very sick. If your cat acts oddly after meeting a tarantula, see a vet fast.

They will know how to help your pet feel better.

Eating a tarantula can be bad for your cat. It needs quick help from a vet.

  • Keep an eye on the heartbeat and breathing of the cat.


Preventive Measures

Safeguarding your feline friend from a potentially hairy situation with a tarantula involves strategy and awareness—let’s explore how you can mitigate the risks and ensure peace between eight legs and four.

By taking proactive steps, we can prevent unnerving encounters that could escalate into unwanted scenarios, keeping both pets out of harm’s way.

How to Prevent Your Cat from Eating Tarantulas

Keeping your cat away from tarantulas is important for their health. Here are steps you can take to make sure they don’t eat these spiders.


  • Keep tarantulas in secure enclosures if you have them as pets. Make sure the cages are strong and always closed.
  • Watch your cat closely when they play outside. If you see tarantulas around, bring your cat indoors.
  • Teach your cat to stay away from spiders with a firm “no” when they show interest.
  • Clear your yard of hiding spots for tarantulas like piles of wood or leaves where spiders might live.
  • Use pet – safe insect control to keep spider numbers down around your home, but never spray chemicals directly on any animal.
  • Consider keeping your cat indoors if you live in an area with lots of tarantulas.
  • Provide plenty of toys and activities inside so your cat doesn’t feel the need to hunt outside.
  • Talk to a vet about other ways to protect your pet. They might know more tips specific for where you live.


Keeping a Cat and Tarantula Safely in the Same Household

Living with a cat and a tarantula under the same roof can be safe. You need to take some safety measures for both pets.


  • Watch your tarantula’s home closely. Make sure the cage is secure so your cat can’t get in.
  • Put the tarantula’s cage in a room that the cat doesn’t go into often. Pick a quiet spot where there’s not much noise or activity.
  • Teach your cat to stay away from the tarantula’s area.
  • Check for loose hairs around and inside the tarantula’s cage. These can hurt your cat if they get in its eyes or nose.
  • Always watch your cat if it seems too interested in the spider’s cage. It might try to touch or open it.
  • If your cat gets near the tarantula, gently move it away every time. This helps teach your cat that it should not go near the spider.
  • Be careful when you’re cleaning out the tarantula’s home or handling it. Make sure your cat is in another room at this time.
  • Keep vet contact details handy just in case something goes wrong like if your cat eats part of the tarantula or gets bitten by one.



So, can a tarantula hurt your cat? It’s rare, but yes. Old world spiders or even those from America but possessing urticating hairs can be dangerous to small pets. Keep cats and dogs away from these creepy-crawlies to be safe.

Remember, it’s all about being careful and knowing what’s risky for your furry friends!
