Colic in Horses

Colic is one of the most common horse conditions for which you will need to call your Veterinarian. Colic is not a disease. It is a clinical sign of many possible diseases. Increasing your knowledge of this common condition of horses could save your horse’s life.

Colic means literally a pain in the abdomen. When a horse "colics," this means that the horse is acting painful and it appears that the pain is coming from the abdomen.

Horse colic can vary greatly in severity. Some colics will go away with just taking your horse for a walk, but other forms of colic will require surgery and can be life threatening. So if you think your horse has colic you should contact your Veterinarian immediately.

There are many possible causes of colic. One possible cause of colic could be from changing its diet. The diet could be too high in grain or maybe there is moldy hay in the feed. Another possible cause is when a segment of the horse's intestine twists in the abdomen. This happens quite frequently in horses. Generally your Veterinarian can diagnose this by ultrasound, palpation, or by use of a stethoscope. To cure this type of colic, surgery is often required. This means you have to take your horse to the Veterinary hospital. Colic surgery in horses is very expensive costing $2,000 at a minimum. In addition the hospitalization is rather extensive and expensive too.

Some common treatments for mild colics could include products that relieve the pain like analgesics such as Banamine or Aspirin. Also, mineral oil is used sometimes if it is thought that extra lubrication in the intestines would help the pain pass. Sometimes in severe cases, intestines can rupture which usually leads to death. But, with proper feeding and care you can prevent most cases of colic.

Usually when calling your Veterinarian about your horse having colic, they will advise you NOT to let your horse try to lie down and roll over. If they are in pain, many horses will try and lay down and roll around on the ground trying to relieve the pain. It is important to prevent this, as a horse can do even more damage to themselves rolling around while in this condition.

A secondary problem often overlooked when a horse has colic is that lameness could develop. This is a disease of the feet which is also a very common problem of horses.

If you think your horse has colic you should contact your Veterinarian immediately, even if it's late at night. When your horse has colic, minutes and hours count toward finding a resolution to the problem.

Another important thing to be aware of, is that some horses are more prone to colic than others. This is a question you should ask a horse owner if you are thinking about buying their horse.

By becoming aware of the common disease conditions in horses you can catch them earlier and provide relief earlier. If you have more questions on colic, contact your Veterinarian.

Feline Heartworm Disease

Cats are very different from dogs when it comes to heartworm disease. Not only do they differ in their susceptibility to the disease, but also in how the disease affects them and how the disease is diagnosed.

There are significant differences between feline heartworm disease and canine heartworm disease. Cats are more resistant to the disease, and typically when they do become infected they have a smaller burden of worms in their bodies. But due to their smaller size, even a few worms can be considered a heavy infection for a cat. Even one worm can cause illness or death in a cat.

Heartworms are caused by a parasite called Dirofilaria immitis. Cats and dogs become infected with this parasite through the bite of an infected mosquito. When an infected mosquito bites the cat, the parasite enters the bloodstream of the cat and grows into an adult worm several centimeters long. These worms tend to accumulate around the vessels of the heart and lungs and cause inflammation of these vessels. In severe cases, they can cause a thromboembolism which results in an acute death.

Since heartworm disease in cats happens less often than in dogs, cats with heartworm disease are often misdiagnosed. Cats with heartworms are often wrongly diagnosed as having asthma or allergic bronchitis. Also, many cats can have heartworms and not appear ill at all.

The true percentage of heartworm positive cats is hard to determine due to diagnostic limitations. In dogs an antigen test is the "gold standard" in diagnosing heartworm disease and it is a very accurate test. Unfortunately in cats these tests are not as accurate. In cats, several tests must be used together to arrive at an accurate diagnosis. These tests can include serology, x-rays and echocardiographs.

Cats that are positive for heartworm disease have many treatment options, but they all have risk associated with them. In mild cases an anti-inflammatory like prednisone may be used. This drug helps support cats by reducing the inflammation of affected vessels. For cats showing severe clinical signs, more extensive treatment and hospitalization are needed. Surgery is also an option to physically remove any worms.

There are many medications on the market to help prevent your cat from getting heartworm disease. Talk to your veterinarian before purchasing heartworm medication as she/he can recommend the most effective one for your area. Monthly preventatives are an option for cats living in areas where heartworm disease is endemic. Even indoor cats may be at risk if windows are left open. Year-round preventatives are increasingly being recommended by more veterinarians. Kittens as young as eight weeks can be started on preventatives.

The most common products used for cats include Interceptor, Heartgard, and Revolution. Interceptor and Heartgard are given orally as chewable medication. Revolution is a topical medication that is applied to the hair over the shoulders. At a minimum, the medication should be started within 30 days of heartworm transmission season and continued until at least 30 days after it ends. In most places this means starting the medication in early Spring and continuing until the end of Fall.

If you live in an endemic area of heartworm disease, be sure to keep your cat on preventatives for the entire year. Talking to your veterinarian is the best source of advice about the prevalence of heartworm in your area.
