Puppies and kittens are born with intestinal worms, and therefore can suffer from vomiting, diarrhea, and loss of weight. Adult dog and cats pick up worms from eggs that stay in the soil after pets have defecated. Pets also pick up worms from eating fleas or eating feces of other pets. Detecting the actual parasite burden of our pets is important to the pet’s health, but to protect human health as well. Undetected infection can lead to animal and human illness.
