Buyer’s Guide

Choosing the Best Cat Wormer can be a tough task. However, keeping the below points in mind, one can surely purchase an effective solution.

What Is a Dewormer for Cats?

A dewormer is a medicine designed to deal with worms in cats. It effectively kills these parasites that infect and cause an infestation in the intestine making your kitty sick.

To understand deeply what worms and dewormers are, you can follow the small insights regarding worm infestation given below.

Types of Worms in Cats

Below are the types of worms commonly found in cats. We have tried to include information such as their source, characteristics, and symptoms.

#1 Roundworms

Roundworm is one of the most common infections in pets, especially puppies. If a pregnant female cat contains roundworms, chances are that its puppies are already born with roundworms. Sometimes, puppies can even get contaminated while feeding on their mother.

Roundworms get their names due to a perfect circular shape if sliced off and watched from the top. Also, they have a pseudocoelom.

Although roundworm infestation can be seen in cats of all ages, it is more common in your cats or kittens. The most common source of contamination is getting in contact with infected feces. Let’s suppose, you take your dog in the park for a walk where there are roundworm-infected feces which gets in the contact with your pet’s paws. Now, reaching home the pet would lick its paws and wham!; there you have your contamination.

The life cycle of roundworms is fairly simple, they start off as an egg, grow into larvae, and further become a well-developed worm. Once they infect a pet, the mature worms produce thousands of eggs that exit through your pet’s feces. Another source of infection can be preying on an infected animal such as a mouse or a bird.

Testing the feces for roundworm eggs is the easiest method to identify a roundworm infestation. Other indications can be a loss of appetite, bloated tummy, and more.

It is important to treat roundworm infestation as these parasitic bacterias can reach human intestines and make you infected as well.

Pyrantel and Piperazine are effective against roundworm infestations.

#2 Tapeworms

A tapeworm needs a flea as a host. The flea carries the infected organism inside its body. Although it does not infect the cat immediately, if the cat eats the flea, it sets off the infected organism free, which makes its way to the small intestine. It sticks itself on the bowel wall and starts growing while feeding on everything that your cat eats.

The body of a tapeworm is made of a chain on small segments. All these small segments contain both male and female counterparts and have the space to carry eggs inside these segments.

Once the tapeworm increases its length up to 70 cm, it won’t be able to move easily and therefore to increase the mobility, it will start getting rid of these segments carrying eggs inside. All these segments are able to move on their own. However, once they are out in the exposed environment they dry out leaving the eggs out, which can be eaten by flea larvae and the life cycle continues again.

The symptoms include cats having diarrhea or constipation along with a stomach ache. In young kittens, bloated tummies can be seen. Sometimes irritation near the anus area can be seen, which makes the cats lick or sub it on external surfaces. The most obvious sign of tapeworm infestation is visible rice like pieces in the feces or near the anus.

Prevention of worm infestation is easier than to deal with one. Therefore, you can ensure some safety grounds. The foremost would be to prevent flea infestation. Fleas are the biggest source of worm infestation. If your cat has had a flea infestation a few weeks back, it is probable that she has been infected with tapeworms as well. Therefore, it essential that you save the kitty from getting any fleas. (Check out some of the flea repellents that we have already reviewed)

Praziquantel is an effective medicine against tapeworm.

#3 Hookworms

Hookworms are one of the scariest parasites to get infected from. They reach your pet through ingestion of hookworm eggs, which can be anywhere in the environment, especially in a contaminated feces or affected soil.

If you have multiple cats at your home, the worm infestation can spread very easily. Moreover, if you use a common cat litter box for all your pets, all the cats can get infected pretty easily.

Signs of Worms and Parasites

Worms do not happen over the night. Sometimes cat parents do not give proper attention to the cat’s health and hence, it results in a worm infestation. And to be honest, it gets worse as time passes. If not given proper treatment at the right time, these tapeworms or roundworms can make your cat sick and make it lose both its digestion and its appetite.

Therefore, it is important that you understand how to get the indications of your cat having a worm infestation

Below are some of the signs that your beloved feline might be affected by a worm infestation.

Vomiting and Diarrhea

The most common indications of worm infestation are vomiting and diarrhea. The worms living in your cat’s intestine disrupt the bowel movement and hence your cat loses its natural digestion flow.

Here, it is important to keep in mind that you may not always find worms in the feces or vomit if the cat is infected with parasites such as worms, especially in the earlier period. Therefore, if your cat is facing severe or frequent vomiting and diarrhea it is vital to get her diagnosed for worm infestation.

Worms Visible in the Feces

Once the intestine is infested with these worms such as tapeworms, roundworms, hookworms, or whipworms, they make your pet sick and cause vomit or diarrhea. Often, you will be able to see worms in the feces making it obvious that your cat has been infected by worms.

Loss of Weight

As worms directly affect intestine, they ingest the food or in simple words eat all the food that you have been feeding your cat. As a result, these worms get bigger and bigger while your cat loses its weight and gets skinnier.

In severe cases, if the infestation is too great, it can make the cat severely ill, which may take weeks to recover. Therefore, if you notice your cat getting any skinnier then immediately consult a vet.

It may happen that you might not be able to inspect the feces of your cat due to work or some other reason. In such cases, loss of weight can indicate worm infestation.

Pot Belly in Kittens

Kittens are highly susceptible to worm infestation. Unlike mature cats, a clear indication for infection with worms can be a pot belly. If you notice your kitten having a bloated tummy, consult a vet.

Irritation Near the Anus

Some worm infestations such as hookworm infestation can cause stomachache along with irritation near the anus. So if you notice your cat licking or biting near the anus area, consult a vet as it may be a sign of worms.

Some other signs can be a dull coat due to lack of nutrition as a result of worm infestation. Hookworms can make the gums bleed. These worms can also cause an intestinal blockage resulting in constipation.
