A Common Household Hazard That Can Be Life-Threatening

Rodenticides (rat and mouse poison) are commonly used around homes, but they can be extremely dangerous to pets. At Veterinary Emergency Referral Center (VERC) in Pensacola, we treat cases of rodenticide exposure far more often than many pet owners realize.

Pets may ingest poison directly by eating bait, or indirectly by eating a poisoned rodent. Either situation can lead to serious, life-threatening illness.

If you suspect your pet has been exposed, seek veterinary care immediately. Early intervention offers the best chance for a successful outcome.

Types of Rat Poison and How They Affect Pets

Not all rodenticides are the same, and each type affects pets differently. This is why bringing the product packaging to your veterinarian is critical for proper treatment.

Anticoagulant Rodenticides

These prevent blood from clotting properly, leading to internal bleeding.

Signs may include:

• Weakness or lethargy

• Pale gums

• Difficulty breathing

• Bruising or bleeding

Symptoms often appear 3–5 days after ingestion, which can delay treatment.

Good news: There is an antidote, but early treatment is essential.

Bromethalin

Bromethalin affects the brain and nervous system, causing swelling in the brain.

Signs may include:

• Weakness

• Loss of coordination

• Tremors

• Seizures

Severity depends on how much is ingested. This type requires immediate veterinary care.

Cholecalciferol (Vitamin D3)

This highly potent toxin causes dangerous increases in calcium levels, leading to:

• Kidney failure

• Calcification of organs

  (heart, kidneys, blood vessels)

Even small amounts can be toxic, making this one of the most dangerous types of rodenticide.

Zinc Phosphide

Commonly used for moles and gophers, this toxin produces phosphine gas in the stomach.

Signs may include:

• Vomiting (often the first sign)

• Abdominal pain

• Weakness or incoordination

• Tremors or seizures

Important: The gas released can also be harmful to humans. Avoid exposure to your pet’s vomit and contact poison control if needed.

Corn Gluten-Based Baits

Often marketed as “safer” alternatives, these can still cause problems.

Possible effects:

• Gastrointestinal upset

• Dehydration

• Intestinal blockage (if large amounts are ingested)

Because these baits often look like more toxic products, never assume a bait is safe based on appearance alone.

What to Do If Your Pet Eats Rat Poison

If you suspect ingestion:

• Remove access immediately

• Bring the packaging or receipt (if available)

  - appearance alone isn’t enough to identify the toxin

• Call your veterinarian or an emergency hospital right away

Preventing Rodenticide Exposure

• Store all poisons securely out of reach

• Only place bait in areas pets cannot access

• Keep track of where and how much bait is placed

• Check bait stations regularly

• Never assume a product is pet-safe
