Discovering worms in your pet's feces can be alarming, but it's a common and treatable issue, especially in puppies and kittens. Intestinal parasites like roundworms, hookworms, and tapeworms are frequently seen in pets and can be effectively eliminated with proper veterinary care. Understanding what to do next will help protect your pet's health and prevent reinfestation.
If you see worms in your pet's feces, stay calm—this is one of the most common health issues in pets and is completely treatable. The worms you're seeing are likely roundworms (which look like spaghetti), tapeworms (resembling rice grains), or hookworms.
First, collect a fresh fecal sample in a clean container or take a clear photo, then contact your veterinarian immediately.
Your vet will perform a fecal examination under a microscope to identify the specific parasite and prescribe the appropriate deworming medication. Never attempt to treat worms with over-the-counter products without veterinary guidance, especially for puppies, kittens, pregnant pets, or senior animals, as incorrect treatment can be dangerous. Most deworming medications work within hours, and you may notice dead worms in the stool within a day, though full recovery takes several days to weeks depending on infestation severity. Your vet will likely schedule follow-up treatments since some parasites require multiple doses to eliminate all life stages.
To prevent reinfection, pick up feces immediately, wash your hands thoroughly after handling your pet, keep their living area clean, maintain a regular deworming schedule recommended by your vet, and use monthly flea prevention since fleas transmit tapeworms. Puppies and kittens should be dewormed every two weeks until three months old, then monthly until six months. Seek emergency care if your pet shows severe symptoms like bloody diarrhea, persistent vomiting, significant weight loss, or lethargy alongside the worm sighting, as heavy infestations can cause serious complications including anemia and intestinal blockages.
