Can Cats Get Bit by Spiders? 5 Surprising Facts You Need to Know

Yes, cats can get bit by spiders. Spiders can bite cats and cause them harm.

Cats are curious creatures known for their playful nature, and their inquisitive behavior often leads them to explore every nook and cranny of their surroundings. However, this curiosity can sometimes cause them to encounter potentially dangerous creatures, such as spiders.

Just like humans, cats can be bitten by spiders, and these bites can cause various complications. While most spider bites are harmless, some spiders can inject venom into a cat’s body, leading to an allergic or toxic reaction. In severe cases, spider bites can even be life-threatening for cats. It is crucial for cat owners to remain vigilant and take necessary precautions to protect their feline companions from spider bites and promptly seek veterinary care if they suspect their cat has been bitten.

Fact 1: Common Spider Species That Bite Cats


A few common spider species can bite cats, including black widow spiders and brown recluse spiders.

Black widow spiders are shiny black with a red or orange hourglass-shaped mark on their abdomens. They are commonly found in warm climates and concealed areas such as garages or sheds.

Brown recluse spiders have a distinctive brown color and a violin-shaped mark on their backs. They are typically found in dark and undisturbed places like closets or basements.

It is essential to understand the behavior of these spider species. Black widow spiders, for example, are known to be shy and only bite when provoked. On the other hand, brown recluse spiders are more aggressive when disturbed.

If you suspect that a cat has been bitten by a spider, it is crucial to seek veterinary attention immediately. Symptoms may vary depending on the spider species and can range from mild irritation to severe allergic reactions.

Fact 2: Symptoms Of Spider Bites In Cats

Spider bites in cats can lead to various symptoms, which can vary in severity. It’s important for cat owners to be able to recognize the signs of spider bites in order to provide appropriate care for their feline companions.

Common symptoms of spider bites in cats include swelling and redness at the site of the bite, pain or discomfort, itching or irritation, and potentially the formation of a blister. In some cases, cats may also exhibit more severe symptoms such as vomiting, diarrhea, lethargy, difficulty breathing, or even collapse.

If you notice any of these symptoms in your cat, it’s important to seek veterinary attention as soon as possible. Your veterinarian can properly diagnose the spider bite and recommend appropriate treatment options to alleviate your cat’s symptoms and prevent any further complications.

Note: It’s important to remember that not all spider bites cause severe reactions in cats, and some bites may not lead to any symptoms at all. However, it’s always better to err on the side of caution and consult with a veterinarian if you suspect your cat has been bitten by a spider.

Fact 3: Treatment And Prevention

When a cat gets bitten by a spider, it is essential to take immediate action. First, visit a veterinarian for professional advice and examination of the bite. They might prescribe treatment options such as antihistamines or localized wound care. Do not attempt to treat the bite on your own, as some home remedies can be harmful to cats.

To prevent spider bites, it’s important to keep your cat’s environment clean and free from spiders. Regularly remove cobwebs from your house, especially in corners and dark areas. Additionally, try to seal any cracks or gaps in walls, windows, or doors to avoid easy access for spiders. Consider using pet-friendly insect repellents if necessary but consult with a veterinarian before doing so.
