Can Cats or Dogs Control Rats at Home?

It seems logical: cats catch mice, terriers hunt rats, so a pet should keep your home free of them. Some people even adopt a cat for this reason. The reality is more complicated, and pets are not a reliable pest control method.

This guide explains what pets can and cannot do.

The short answer

Cats and some dogs may catch the occasional rat or mouse and their presence can make rodents more cautious, but they rarely control an established infestation. Rats are large, wary and can fight back, they hide in places pets cannot reach, and they breed quickly. Pets are not a substitute for proofing and proper control. Hunting rats also carries risks for pets, including bites, parasites, diseases and poisoning from eating poisoned rodents. Rely on sealing, sanitation, traps or professionals, and keep pets safe.

What pets can do

• Catch a few mice or young rats, especially hunting breeds.
• Deter some rodents by presence, scent and noise, particularly in small areas.
• Alert you to rodents by interest in a spot.

Why pets are not enough

1. Rats are big, wary and may fight back, and many cats ignore them.
2. Rodents hide in wall voids, roof spaces and burrows pets cannot reach.
3. Rats breed faster than pets can catch them.
4. Pets are not active continuously or in every area.
5. Rats will return if food and entry points remain.

Risks to pets

• Bites and injuries: Rats can bite and scratch.
• Disease: Rodents can carry germs, including leptospirosis, which can affect dogs and people.
• Parasites: Fleas, ticks and worms.
• Poisoning: Pets can be harmed by eating poisoned rodents or bait.

Pet food and rats

Pet food and bowls attract rats. Feed at set times, remove leftovers, store food in sealed containers and keep feeding areas clean.

What actually controls rats

• Seal entry points with mesh and sealant.
• Remove food, water and shelter.
• Use snap traps or professional methods.
• Keep waste secure and the compound tidy.

If you have pets and need control

• Tell the pest controller about your pets.
• Use enclosed, tamper-resistant stations out of reach, or traps instead of loose poison.
• Ask a vet about parasite and vaccine protection.
• Contact a vet immediately if a pet eats a rodent that may have been poisoned.

When to call a professional

If rats are in your home, call a professional rather than rely on a pet.
