Cats with white fur and pink skin are particularly prone to sunburn of their nose, ears, lips, and other areas of their face, which then puts them at risk for sunburn related skin cancers. The easiest way to prevent this is to limit exposure to intense sunlight for prolonged time periods. Luckily, cats are usually less active during hot weather and seek shade to sleep, so confinement and avoidance is not difficult.
Roundworms are seen mostly in kittens as a result of nursing infected queens. Routine kitten worming protocols are very effective in eliminating the problem. Adult cats that show poor condition and GI signs (diarrhea) should be tested. Transmission is cat to cat.
Cats that roam outside and get into rodent dens or deer beds can be found with fleas in Central Oregon, but otherwise, fleas are rare here. Control with topical medication can be used if needed.
As with fleas, ticks are rare and are generally found on cats that spend time in areas frequented by wildlife. Control is as for fleas with the same topical med.
Tapeworms are seen in cats that are active hunters who consume rodents. In other areas, fleas can also transmit tapeworms to cats. Tapeworm segments (proglottids) are seen in live or dried form attached to the hair around the cat’s backside or directly on fresh feces. They appear as small grains of rice (dried) or small flatworms (live) that are actually egg packets that must be consumed by a mouse or flea to complete the cycle. No cat to cat, cat to dog or cat to human is possible.
The larval “cattle grub” will sometimes find cats as an abnormal host and be found as a mass under the skin with a small hole at one end. Careful surgical removal is advised. This is the same parasite as described affecting dogs
This nearly microscopic “walking dandruff” mite is the cause of severe itchiness and focal skin lesions of cats. They are detected by microscopic examination of skin scrapes of lesions. Occasionally these mites cause similar lesions on humans who acquire the infestation from an affected cat. They are effectively treated with oral medication. Cats can sometimes be asymptomatic carriers but still transmit the disease to other cats or people.
This common ear parasite is seen frequently in Central Oregon cats and rarely in dogs. They are very contagious from cat to cat, less so cat to dog, and can survive in the environment for transmission. Cats with ear mites will scratch at their ears, causing lesions at the base of the ear, and the ear will contain a dark “coffee-ground” appearing accumulation of debris. Once mites have been identified they are most effectively treated with two or three doses of oral medication administered at two week intervals. It is very important to treat all of the cats in the household at the same time to prevent ongoing re-infection.
Ringworm is a very common fungal skin infection of cats and dogs that is also transmissible to people. Infection is most common in young animals and is generally seen as a round hairless, scaly lesion on the head, neck or back that may or may not be itchy. Cats can be asymptomatic carriers and transmit the infection to people despite the lack of skin lesions. The disease is most severe in cats that have weak immune systems, for whatever reason, and is generally self-
FeLV is prevalent in Central Oregon and affects both urban and rural cat populations. The disease is manifested in many forms: abortion and stillbirths in infected pregnant queens, fading kittens, immunodeficiency and opportunistic secondary infections, and cancer. The disease is spread by saliva (grooming, playing, fighting, sharing water bowls), contact with infected blood (fighting), and through the placenta during pregnancy. The disease is readily prevented with vaccination and avoiding contact.
FIV is prevalent to a similar extent as FeLV in both urban and rural cats in Central Oregon. The disease is most often associated with free-roaming intact male cats that are active in breeding and fighting. Clinical signs are those of secondary opportunistic infections that occur due to immunodeficiency as the name implies. There is no vaccine at this time, so neutering and keeping companion cats from contact with free-roaming carriers are our best prevention methods. Keeping cats inside at night, not leaving food outside to attract feral cats, and eliminating feral cat populations are helpful in achieving this goal. Testing for FIV is often combined with FeLV when introducing a new cat to a household.
FIP is prevalent in both urban and rural populations in Central Oregon cats and is often an opportunistic secondary disease that is seen in FeLV and/or FIV infected cats. It has many presentations and can be difficult to diagnose in its early stages. The disease is ultimately fatal, but may be present in apparently healthy carriers for quite some time. Young cats, 6 months to 2 years, are most susceptible, particularly Asian breeds in multi-cat situations such as catteries and shelters . The biology of the disease is very complex and developing clinical signs of disease is dependent upon mutation of an otherwise innocuous Feline Coronavirus within the host and the ability of the immune system of the host to fight it off. Vaccination is available but prevents accurate detection of the disease, so is recommended in very limited situations. Accurately diagnosing FIP is clinically difficult in its early stages, and even sometimes with overt disease. This is one disease that we have seen spread on multiple occasions from cats adopted from animal shelter/rescue organizations to cats already in a household, so pre-introduction isolation, evaluation and testing is advised.
Coyotes, bobcats, mountain lions and large birds of prey, (eagles, Great Horned Owls) are serious hazards for domestic cats in Central Oregon, even in some residential areas within city limits. Young cats are especially vulnerable as they are often oblivious to danger. Keeping cats indoors, particularly at night, and assuring availability of a safe haven where the cat can hide in during the day are good protective measures for all cats.
