Criteria Used for Evaluation

Materials

Praziquantel is a common compound used in the production of worm medication for pets. It is an anthelmintic proven effective at combating worm in infestations by inducing paralysis of the worms. This affects their ability to cling to the walls of places such as the GI tract and while dislodged, the body can easily flush them out through designated channels such as feces.

Diatomaceous earth is a type of sand that can be formed by fossilized algae which is a natural source as opposed to a chemical based one. This compound causes the same reaction commonly used chemicals in that it dries out the external skin of parasites or dehydrates them causing their death. These can then be flushed out by the body through excretion.

Wormwood herb is a plant that can be added to these types of solution to offer additional benefits in the area of digestion. Since this is the area where most treatments are concentrated due to the worm population in the digestive tract it is ideal for settling the stomach and reducing symptoms such as vomiting and spasms. It can also treat appetite loss which is another symptom produced by worm infestation.

Probiotics and vitamins are also commonly included in the formula of many treatments as this help to restore balance and give the body the ammunition it needs to fight off and flush out these contaminants. This is especially useful in cases where a paralyzing agent is used as the parasites are left alive and this method relies heavily on the body’s natural ability to expel these parasites through the feces.

Ease of Use

Liquid formulas have a number of benefits over their tablet counterparts, one of which is their ease of ingestion. Swallowing a liquid is easier to swallow than a tablet and can easily be mixed in with water or food to disguise the taste. This is a valuable asset when you have pets that don’t like taking medication. In this state, it is also easier for the body to absorb the contents of the treatment as it does not need to break down a capsulated structure.

Some medicines come in tablet form which does not mean that they are more of a challenge as they come with their own features that can aid users through treatment. There are selections, for example, that can be easily cut into halves which has two main benefits. The first and most important is the ease of adjusting the dose according to the weight of your pet.

While most treatments are designed to be taken orally there are those that need not be ingested at all. They strike at the root of the problem by getting rid of carriers such as fleas and ticks. Another benefit is that they can eradicate both internal and external parasites but what makes them so easy to use is that they take the form of a collar. There are multiple sizes which ensure most sized pets are well accommodated.

Use

Roundworms are one of the most common of the parasites found in pets and almost every worm medication on the market will cater to these. Common symptoms of this infestation include lethargy, abdominal swelling, and vomiting. There are some treatments that have dual action formulas that will also eliminate tapeworms while others can tackle up to four types of parasites. These often include hookworms and whipworms.

Although the main purpose of taking these types of medications is to rid the body of parasites, they can do a lot of internal damage that also needs to be addressed. This is why many manufacturers are fortifying their products with added ingredients such as probiotics and vitamins which can be used to boost the immune system and heal the damage done by parasitic activity. When used as a preventative measure these do wonders to ensure that your pet stays healthy on a month to month basis.

Advanced Features

It can be a challenge to find a system that works well with your pet as they may not be conducive to taking medication. Constant doses may turn into a workout and a hassle. Some manufacturers have designed their product to build up or maintain a level of concentration over a period of time. With some selections, a single dose can last up to two weeks. This makes it easy for both you and your friend to keep up with the recommended schedule.

There are some manufacturers that package their product individually which eliminates the need for guesswork by pet owners. You will still have to weigh your pet to discern how much of the package needs to be used, however, will singe packets it makes it easier for you to track what has been given and what still needs to be taken. You will also be aware of how much of the product you need for the number of pets that you have and you will also know how long each order will last.

While there are some formulas that treat only one type of parasite, there are quite a few that are designed to tackle all four of the most common types of parasites your pet may carry. That does not mean they will not carry worms that are not included in this group which is why some types of treatments go above and beyond with an increased capability that covers a range of up to eleven parasites. They can even tackle external as well as internal forms of parasites so your pet is well protected.

Typically, you can find treatments in a variety of forms with the most common being liquid and tablet form. This is due to the fact that they are easy to use and adjustable. There are some formulas that may be provided in powder form as these are ideal for mixing into food. There are a few brands thought that have pushed the envelope and developed formulas that can be administered in a gel form. This is equally as effective and creates a creative option that promotes ease of use.

Capacity

It is certainly not a burden when it comes to providing for your pet and their needs, however, it can be overwhelming when you have to constantly keep track of orders that need to be filled every month. Faltering on this schedule can sometimes cause a setback making you have to restart the entire process. You most likely want to make sure that a product can last for some time. That is one factor that makes liquid treatments so valuable.

They generally come in large bottles that hold at least four ounces of solution. That may not seem like much, however, when doses are measured in quarter teaspoons that can really allow the product to “stretch”. Even when you factor in the age, body weight and the number of friends you have, using as much as a whole teaspoon at a time will still ensure you get up to twenty-four uses out of that single four-ounce bottle.

As your cat gets older their schedule becomes less frequent as you now have the opportunity to go into a preventative mode. This lengthens the life span on your item even further. These are just a few factors you can take into consideration when searching for an item that will best suit your needs.

Whether a treatment is in liquid, tablet, powder or gel form, the concentration per dosage remains the same in a standard dose. This means that the same volume of formula in any form will provide you with a consistent number of uses per container. Some items have as little as 2 ounces per container but there are brands that will provide treatment that number up to 8 ounces per container.
