How To Stop My Guinea Pig From Attracting Rats?

Guinea Pig

As per the information you have read so far, you might have understood that guinea pigs do not attract rats.

But the environment in which they reside can undoubtedly act as an attractant for the rats. 

That is why it is the responsibility of the owners to keep their guinea pigs protected against potential rat attacks by implementing the following measures:

By controlling the amount of food available for the rat. You can do this by:

  • Keeping the food containers closed. You can keep the food items secured and sealed. This is why not only are you saving a food source for your guinea pig but preventing a full-fledged attack by the rats on the loose. 

  • Make sure that no food pellets are lying around. As a rat’s sense of smell is very sharp, it will be attracted to them instantly, and a starving rat will not mind attacking a guinea pig alongside a few food scraps.

  • Avoiding stray food. This can be done by keeping track of all the dropped food. Although this can be hard, it can be avoided if one has a keen eye and takes enough precautions.
  • Getting rid of unnecessary food 

The food that goes missing under furniture or carpets can be avoided by feeding guinea pigs in an open space. Guinea pigs waste a lot of food while they are munching.

Thus a slight mop or vacuum after they are done eating can avoid attracting rats to their cages. 

Though this is not perfect avoidance, implementing such measures can keep your guinea pigs out of the blue and ensure a longer life span, free from rat attacks.

  • Keep a cat

A cat hunts all the rats down for food to keep any rat miles away from a guinea pig.

The guinea pigs can consume a rat bait even after a rat has fed on it. 

Can Wild Rats Kill Guinea Pigs?

Whether the rats are domesticated or wild or belong to any other species, they will attack and kill the guinea pigs as their basic predator-prey relationship remains intact. 

However, the wild rats are more ferocious and attack guinea pigs so strongly that they die out much quicker as they cannot recover from the inflicted wounds.

Also, a wild rat is much more giant in size, and it is very difficult for a guinea pig to escape its attack.
