Health problems among guinea pigs that live alone are usually related to aging, dental disease, reproductive disorders, injury, or improper care. Infectious diseases caused by certain viruses and bacteria usually occur only in guinea pigs that live with other guinea pigs. Intestinal parasites are not common. Tumors are rare in young guinea pigs but are more common in guinea pigs that are more than 5 years old. Treatment of infectious diseases can be complicated by the fact that guinea pigs are more sensitive to antibiotics than other types of pets.

Prevention of health problems in guinea pigs is key. A proper diet that does not change from day to day, clean water, bedding materials that are gentle on your pets skin, frequent cleaning and disinfecting of the cage, a low-stress environment, and sufficient exercise all help prevent illness.

Rats Mice And Hamsters

The retina of rats, mice, and hamsters is holangiotic, with arteries and venules radiating from the optic nerve like spokes on a wheel. Rats have three lacrimal glands: intraorbital, extraorbital, and harderian.

Inbred strains of rats and mice are commonly used in commercial laboratories to study naturally occurring ophthalmologic diseases. Diseases involving all parts of the eye have been described. Common abnormalities include retinal degeneration, as in the RCS rat, microphthalmos, and cataract. In addition to specific genetically determined ocular abnormalities in inbred strains, other spontaneous abnormalities occur. Ophthalmic examination of 6000 Sprague-Dawley rats revealed a focal linear retinopathy in 3% and a fundic coloboma in 0.5% of animals examined. Spontaneous corneal degeneration has been described in Sprague-Dawley and Wistar rats, and corneal dystrophy has been described in Fischer 344 rats. Experimental infections also lead to ophthalmic abnormalities. Blepharitis with crust formation in the medial canthus and partial periocular alopecia were observed in mice experimentally infected with Trypanosoma brucei.

Of clinical significance is the effect of xylazine on the lens in rats and mice. A reversible cataract has been observed after systemic use of xylazine. Transcorneal water loss and altered aqueous humor composition caused by corneal exposure have been suggested as a pathogenesis of cataract formation.

Metabolic And Nutritional Disorders

Guinea pigs of all ages require a dietary source of vitamin C. The stability of vitamin C in diets varies with composition of the diet, storage temperature, and humidity. The feed content of vitamin C is reduced by dampness, heat, and light. In fortified diets, approximately half of the initial vitamin C may be oxidized and lost 90 days after the diet has been mixed and stored at temperatures > 22°C . Water in an open container may lose up to 50% of its vitamin C content in 24 hours. Aqueous solutions of vitamin C will more rapidly deteriorate in metal, hard water, or heat and are more stable in neutral to alkaline solutions.

Clinical signs of hypovitaminosis C include diarrhea, alopecia, and pain animals are thin and unkempt. Petechiae on mucous membranes are not always seen, although hematuria may be present. Guinea pigs will show signs of vitamin C deficiency within 2 weeks if it is not provided. Serum hypercholesterolemia and hypertriglyceridemia is seen in vitamin Cdeficient guinea pigs after an overnight fast. Guinea pigs need ~10 mg vitamin C/kg body weight daily for maintenance and 30 mg vitamin C/kg body weight daily for pregnancy. Vegetables high in vitamin C include red or green capsicums, tomatoes, spinach, and asparagus.

How can you keep a hygienic environment for your guinea pig?

To keep a hygienic and clean environment for your pig, consider the following

Set dust-free bedding for your guinea pig

Guinea pigs are sensitive to specks of dust and may react to any little dust in their eyes, therefore, you must set dust-free bedding for your pet.

Typical examples of dust-free beddings are newspapers or shredded papers.

Its rather important to note that the newspaper or shredded papers are not absorbent.

This implies that these dust-free bedding cant absorb urine or odor.

Parasitic Infections In Guinea Pigs

Mange, caused by the sarcoptid mite Trixacarus caviae, is common in guinea pigs. The clinical signs are dramatic: intense pruritus, widespread alopecia, and hyperkeratosis. T caviae is transmitted through direct animal-to-animal contact from sow to weanlings during feeding, and through contact with infested cage material such as bedding. The mites may be capable of existing subclinically, becoming active with stressors , immunosuppression, or other underlying diseases. In affected animals that exhibit hematologic changes such as heterophilia, monocytosis, eosinophilia, and basophilia, vigorous scratching may trigger convulsive seizures. The seizures are controlled by diazepam . The clinical presumptive diagnosis should be confirmed with several skin scrapings, usually revealing a massive T caviae infestation. Treatment involves ivermectin , or spot-on dermal treatment with either selamectin . The guinea pig should also have a whole body washing with fipronil repeated twice at intervals of 710 days. Fipronil should not be used when open skin wounds are present.

Other ectoparasitic diseases are infrequent in guinea pigs. Infestation with the fur mite Chirodiscoides caviae may result in pruritus and alopecia along the posterior trunk of the body, while underlying skin is relatively unaffected. Subclinical cases may be asymptomatic. Treatment is with selamectin administered twice at 2-week intervals.
