Yes, cats do kill and sometimes eat spiders. They often use them as playthings but may outright kill them while playing or eat them for a tasty snack. Fortunately, most spiders don’t pose a threat to your kitty.
Cats Don’t Always Eat Spiders Because They Are Hungry
You can find a spider laying around the house after you’ve seen your feline companion playing with it. A cat is going to lose interest in playing if they accidentally kill the spider.
The average household spider isn’t really dangerous for your cat. Before a spider could bite your cat, it would have to sneak up on it and get past all their fur before getting to the skin.
