Cats can eat spiders, and it is quite common for cats to catch and eat them. Most spiders found in households are safe for cats because their stomach acid neutralizes any venom that might be present. However, there are exceptions with certain venomous spiders such as the False Widow, Black Widow, and Brown Recluse, which could potentially harm cats if bitten. The main risk is not from eating the spider itself but from being bitten by one, which can cause symptoms like swelling, vomiting, or lethargy and would require veterinary attention. Overall, while cats are natural hunters and often eat spiders without harm, it is advisable to observe any adverse symptoms after a cat consumes or interacts with a spider and consult a vet if symptoms appear.
Why Cats Eat Spiders
Cats are instinctive hunters, and moving spiders trigger their predatory behavior. Playing with and eating spiders provides mental and physical stimulation.
Potential Risks
- Venomous spider bites can cause swelling, pain, vomiting, or more serious symptoms.
- Most spider venom is broken down safely in the cat’s stomach.
- Bites in the mouth during eating pose a higher risk.
- Certain spider species like False Widows and Black Widows are more dangerous.
What to Do
If a cat shows signs of distress such as vomiting, swelling, or unusual behavior after encountering a spider, consulting a veterinarian promptly is advised.
