The Cat’s Curiosity

Your cat’s inquisitiveness and predatory instincts are a testament to its wild ancestry. Whether it’s a playful pounce or a vigilant stare at a crawling insect, your cat’s fascination with these tiny creatures is undeniable.

Studies have shown that cats have a natural attraction to insects, which they consider as prey. This curiosity can sometimes lead to a cat attempting to “play” with a spider by batting it around. However, the risk lies in the spider’s response if it feels threatened.

As per research published in the “Journal of Arachnology,” wolf spiders, like other spiders, may bite when provoked or cornered[^2^]. Their venom is primarily designed to immobilize their prey, and its effects on cats can vary depending on the species of wolf spider and the individual cat’s sensitivity.
