Q: Do spiders bite dogs and cats as well? How would l know if my cat or dog has been bitten by a spider?
A: Yes, they could bite your pet, but it is very rare for spiders to bite pets, as they have fur or hair, making it harder for spiders to get to the skin to bite them. There are no definitive signs that you will see that will confirm that your pet has a spider bite, so if you see a small wound that is not healing, take your pet to a vet.
