If your curious cat has chewed on or swallowed a Tums tablet, you may be feeling alarmed. Tums are a common human antacid used for heartburn and sour stomach, but are they safe for pets? The big question cat owners ask is: Are Tums poisonous to cats? The short answer is that Tums are not usually poisonous in small amounts, but they are not safe or recommended for feline use. Cats have very different nutritional and medical needs, and giving them Tums may do more harm than good. Let’s explore why.
1. What Are Tums?
Tums are over-the-counter antacid tablets made with calcium carbonate as the active ingredient. In people, calcium carbonate neutralizes stomach acid and relieves:
- Heartburn
- Acid indigestion
- Sour stomach
Each chewable tablet also contains inactive ingredients such as sugars, starches, flavorings, and sometimes artificial sweeteners. These additives are where problems can arise for cats.
2. Are Tums Poisonous to Cats?
No, Tums are not generally poisonous in tiny amounts. If your cat licks a bit of Tums dust or nibbles on a piece of a tablet, it’s unlikely to cause a medical emergency. Calcium carbonate itself is not toxic at low levels. However, Tums are not safe or effective for cats and may cause health issues if consumed in larger amounts or over time.
Potential risks include:
- Excess calcium: Can stress the kidneys and lead to kidney stones or other imbalances.
- Additives: Artificial sweeteners, dyes, or flavorings may upset digestion or, in rare cases, be toxic.
- Underlying health conditions: Cats with kidney disease or metabolic problems are especially vulnerable.
3. Why Cats Should Not Be Given Tums as Medicine
Some pet owners wonder if Tums could help cats with vomiting or stomach upset. The answer is no. Here’s why:
- Ineffective for cats: Tums do not address common feline digestive issues.
- Wrong calcium balance: Cats have specific dietary calcium and phosphorus requirements that Tums can disrupt.
- Better options exist: Veterinarians may prescribe safe feline-friendly medications instead.
4. What Happens If a Cat Eats Tums?
If your cat eats a small amount of Tums, most likely nothing serious will happen. However, possible side effects include:
- Vomiting
- Diarrhea or constipation
- Lack of appetite
- Lethargy
- Excessive drooling
In larger amounts, or in cats with kidney issues, symptoms may be more severe, including weakness, tremors, or increased urination. Always monitor your pet closely.
5. What To Do If Your Cat Ate Tums
If your cat ingested Tums, here are the steps to take:
- Check the package: Look for xylitol, which is toxic to pets.
- Estimate the amount: Try to determine how much your cat consumed.
- Call your vet: Provide your vet with your cat’s weight, age, and medical history.
- Monitor symptoms: Watch for vomiting, lethargy, or other unusual behaviors.
- Seek emergency help: If your cat ate a large number of tablets or shows severe symptoms, contact an emergency veterinary clinic right away.
6. Safer Alternatives for Cats With Digestive Issues
Instead of Tums, veterinarians may recommend these approaches for cats:
- Prescription medications: Such as famotidine (Pepcid) or omeprazole in correct feline doses.
- Diet changes: Switching to sensitive stomach formulas or prescription diets.
- Probiotics: Designed for cats to support healthy digestion.
- Hydration: Ensuring cats drink enough water, especially if prone to urinary or kidney problems.
Never give your cat human medications without consulting your veterinarian first.

10. Conclusion
Are Tums poisonous to cats? Not usually in small amounts. A lick or one tablet is unlikely to cause severe harm. However, Tums are not safe, effective, or recommended for cats.
