It’s a scenario many cat owners dread: you notice your curious feline playing with a string, and suddenly, it's gone. Cats are notorious for their love of string, but swallowing it can lead to serious health risks. If your cat has swallowed a string, don’t panic — but do act quickly. Here’s everything you need to know and do to keep your pet safe.

⚠️ What to Watch For

When a cat swallows a string, it can pose a variety of risks, from mild irritation to life-threatening complications like intestinal blockages. The signs to watch for depend on how far the string has traveled through their digestive system.

Here are some symptoms that may indicate an issue:

  • Vomiting or gagging
  • Loss of appetite or refusal to eat
  • Lethargy or unusual hiding
  • Abdominal pain (e.g., hunching, growling when touched)
  • String visible hanging from the mouth or anus
  • Diarrhea or constipation

If you notice any of these symptoms, it's important to monitor your cat closely and take action immediately if their condition worsens.

🔍 Possible Causes

Why do cats swallow string in the first place? Cats are naturally drawn to string-like objects because they mimic the movements of prey, such as worms or snakes. But when ingested, string can become dangerous.

Here are some common sources of string that cats might swallow:

  • Sewing thread or yarn
  • Dental floss
  • Holiday decorations like tinsel or ribbon
  • Hair ties or shoelaces

When swallowed, string can become a "linear foreign body," which means it can get tangled in the intestines or cause bunching, leading to blockages or tears.

✅ What You Can Do at Home

If you suspect or know your cat has swallowed a string, here’s what to do — and what not to do — before heading to the vet.

Steps to take:

  • Check their mouth: If you see the string hanging from their mouth, gently try to remove it. But if the string resists or seems stuck, stop pulling immediately. Forcing it could cause injury to the throat or esophagus.
  • Monitor their behavior: Keep a close eye on your cat for any signs of distress, such as vomiting, lethargy, or abdominal pain.
  • Examine the litter box: Look for signs that the string has passed naturally in their stool. If it has, the danger may be over, but continue observing your cat for any lingering symptoms.

What NOT to do:

  • Do not pull the string if it’s hanging from their anus. This could damage the intestinal lining if the string is tangled inside.
  • Do not induce vomiting unless explicitly instructed by a vet. This could worsen the situation if the string is already lodged in their digestive tract.
  • Do not wait too long to seek veterinary help if your cat shows signs of distress.

💡 When to Call a Vet

Sometimes, professional help is the safest option. Call a vet immediately if:

  • Your cat is vomiting repeatedly
  • They’re lethargic or refusing to eat
  • You can see string hanging from their mouth or anus, but it won’t come out easily
  • You suspect the string is causing a blockage or other complications

Your vet may recommend an X-ray or ultrasound to determine the location of the string. In severe cases, surgery may be required to remove it safely.

According to VCA Animal Hospitals, linear foreign bodies like string are a common and serious issue in cats, and prompt veterinary care is crucial for the best outcome (source).

FAQs

Q: Can a cat die from swallowing a string?
A: Yes, if the string causes an intestinal blockage or perforation, it can be life-threatening. This is why prompt veterinary care is essential if your cat shows signs of distress.

Q: How long does it take for a cat to pass a string?
A: If the string is small and doesn’t cause complications, it may pass within 10–24 hours. However, this depends on the size of the string and your cat’s digestive health. Always consult a vet if you're unsure.
