Why Rat Bait Is So Dangerous

Rat bait, also known as rodenticide, contains potent chemicals designed to kill rodents by interfering with their blood clotting ability. The problem? It works the same way in pets.

If a dog or cat eats rat bait—or even a poisoned rodent—they can suffer from internal bleeding, which may not show symptoms until it’s too late. Some newer types of bait can also affect the nervous system, causing tremors, seizures, or kidney failure.
 

Common Symptoms of Poisoning

The signs of poisoning may appear slowly, sometimes days after ingestion. Be on the lookout for:

• Weakness or lethargy

• Pale gums

• Coughing or difficulty breathing

• Vomiting or blood in stools

• Bruising easily or bleeding from the nose or gums

• Seizures (in the case of some newer rodenticides)

If you suspect your pet has been exposed to rat bait, act immediately—early treatment can be lifesaving.

How Exposure Happens

• Direct ingestion of bait (this is especially common with curious puppies).

• Secondary poisoning by eating a rodent that has consumed bait.

• Bait placed in unsecured areas, like garages, sheds, or under the house.

 

Keeping Pets Safe

• Avoid using rat bait at all, if possible—opt for pet-safe traps instead.

• If you must use bait, place it in pet-proof containers and areas inaccessible to your pets.

• Supervise your pets outdoors, especially in areas where bait may be used (like parks or neighbouring properties).

• Be cautious if your pet roams freely—many poisonings happen when pets visit other homes or farms.

What to Do If You Suspect Poisoning

Time is critical. Contact your vet immediately with as much information as possible—what your pet ate, when, and how much. Bring the bait packaging if available. In many cases, treatment includes Vitamin K therapy, blood transfusions, or hospitalisation.
