Cats can fall prey to Ascaris worms, and this can cause a host of health issues. In this article, we will dig deep into why cats get infected by these pesky parasites. Understanding these reasons can help cat owners take steps to protect their feline friends from Ascaris worm infections.
Poor Hygiene Practices
Litter Box Hygiene
Cats rely on litter boxes to relieve themselves. But if the litter box isn’t cleaned regularly, it becomes a breeding ground for Ascaris worms. Worm eggs can be present in the feces of an infected cat. When new eggs are added to the litter box daily and not removed, the risk of other cats getting infected rises. Cats may step in the litter, and if they lick their paws later, they can ingest the eggs. Even a small amount of contaminated litter in their mouths is enough to start an infection.
Self-Grooming Habits
Cats are known for their self – grooming. But sometimes, this natural behavior can backfire. If a cat has been in an area where Ascaris eggs are present, like a dirty yard or a place where other infected cats have been, and then licks its fur, it may swallow the eggs. Some cats are not as thorough in their grooming, leaving dirt and potential worm eggs on their bodies. They may also groom in a hurry, missing areas where eggs could be hiding.
Environment Hygiene
The overall cleanliness of the cat’s living environment matters. If the living space is cluttered and dirty, it’s easier for Ascaris eggs to survive. Dusty corners, piles of old toys, and uncleaned bedding can all harbor the eggs. Cats that live in such an environment are more likely to come into contact with the eggs and get infected.
Exposure to Infested Environment
Outdoor Exposure
Cats that spend time outdoors are at a higher risk of Ascaris worm infection. Outdoor areas, such as gardens, parks, and alleys, can be full of Ascaris eggs. These eggs can be present in the soil, on grass, or even on plants. Cats may sniff, lick, or play with objects in these areas, and in the process, ingest the eggs. They may also dig in the soil, and then when they groom themselves, the eggs enter their bodies.
Contact with Infected Animals
Cats that interact with other infected animals are at risk. Stray cats, in particular, are often carriers of Ascaris worms. If a domestic cat comes into contact with a stray cat, it can pick up the worm eggs. This can happen through direct contact, like sniffing or fighting, or indirectly, by being in the same area where the stray cat has left feces. Even wild animals, such as mice and birds, can carry Ascaris eggs. Cats that hunt and eat these animals are very likely to become infected.
Shared Living Spaces
In multi-cat households or shelters, the risk of Ascaris worm transmission is higher. If one cat is infected, the eggs can spread quickly. The cats may share litter boxes, food bowls, and sleeping areas. This close contact allows the eggs to move from one cat to another easily.
Consumption of Infested Food or Water
Contaminated Food
Cats that eat contaminated food are at risk of Ascaris worm infection. Some commercial cat foods may be contaminated during production or storage. If the food is stored in an unclean environment, Ascaris eggs can find their way into the food. Also, if cats are fed raw or undercooked meat, they may ingest the eggs. Raw meat from animals that are carriers of Ascaris worms can pass the eggs to the cat.
Unclean Water
Water is essential for cats, but if it’s not clean, it can be a source of Ascaris eggs. Outdoor water sources, such as puddles, ponds, or even dirty water bowls, can contain the eggs. Cats that drink from these sources are putting themselves at risk. Even indoor cats may be at risk if their water bowls are not cleaned regularly. Algae and bacteria can grow in the water, and along with them, Ascaris eggs may be present.
Lack of Immune System Function
Young Cats
Kittens have immature immune systems. This makes them more vulnerable to Ascaris worm infections. They may not be able to fight off the eggs as effectively as adult cats. Kittens can get Ascaris worms from their mother, either before they are born or through her milk. Once the eggs hatch inside the kitten’s body, the weak immune system may struggle to contain the growing worms.
Sick Cats
Cats that are already sick or have underlying health conditions often have weakened immune systems. Diseases like feline leukemia, feline immunodeficiency virus, and other infections can make a cat more susceptible to Ascaris worms. When the immune system is busy fighting the primary illness, it may not be able to mount a strong defense against the worm eggs.
Stress-Related Immune Suppression
Stress can also affect a cat’s immune system. Changes in the cat’s environment, such as moving to a new home, the introduction of a new pet, or loud noises, can cause stress. When a cat is stressed, its immune system may become weaker. This makes it easier for Ascaris eggs to take hold and cause an infection.
Genetic Factors
Inherited Susceptibility
Some cats may be genetically more susceptible to Ascaris worm infections. Just like humans can inherit certain traits, cats can inherit a tendency to be more vulnerable to parasites. Breeders may unknowingly pass on genes that make cats more likely to get infected. However, more research is needed in this area to fully understand the role of genetics in Ascaris worm infections in cats.
Individual Differences
Even within the same litter, there can be individual differences in how cats respond to Ascaris worms. Some cats may have a natural ability to fight off the eggs better than others. These differences could be due to subtle genetic variations that affect the cat’s immune response or how its body processes the eggs.
Conclusion
Cats can get infected with Ascaris worms due to a combination of factors. From poor hygiene to a weakened immune system, each factor plays a role in the spread of these parasites. By understanding these reasons, cat owners can take proactive steps to reduce the risk of their cats getting infected and keep their feline companions healthy.
