Guinea Pig Care

Guinea pigs are social, vocal, and surprisingly complex medically. Dr. Davis provides knowledgeable care for guinea pigs — from routine wellness to dental disease and respiratory infections.

Guinea Pig Health Basics

Guinea pigs (cavies) are prey animals that hide illness instinctively. They have a relatively short lifespan of 4–7 years and can develop serious health problems quickly. They are also unique among common pets in that they cannot synthesize their own vitamin C — dietary deficiency causes scurvy, a serious and preventable disease. Annual wellness exams are essential for catching problems early.

Dental Disease in Guinea Pigs

Like rabbits, guinea pigs have continuously growing teeth. Dental malocclusion — where the cheek teeth overgrow and form sharp spurs that cut into the tongue and cheeks — is one of the most common and serious guinea pig health problems. Signs include drooling, difficulty eating, weight loss, and a wet chin. Dental disease in guinea pigs requires veterinary treatment under anesthesia and often recurs, requiring regular monitoring.

Vitamin C: The Guinea Pig Essential

Guinea pigs cannot synthesize vitamin C and must obtain it entirely from their diet. Deficiency causes scurvy, which presents as rough coat, lethargy, reluctance to move (due to joint pain), dental problems, and poor wound healing. Fresh vegetables high in vitamin C (bell peppers, leafy greens) should be offered daily. Vitamin C supplements can be added to water or given directly. Pellets lose their vitamin C potency quickly after opening.

Frequently Asked Questions

How often should my guinea pig see a vet?
Annual wellness exams are recommended for guinea pigs. Because they hide illness and have relatively short lifespans, yearly exams are the best way to catch problems early. Guinea pigs over age 3 may benefit from semi-annual exams.
What are signs that my guinea pig is sick?
Signs of illness include: not eating or drinking, weight loss, lethargy, labored breathing, nasal or eye discharge, drooling or wet chin (dental disease), hair loss, skin crusting, changes in droppings, and vocalizing when touched. Any of these warrants a veterinary exam.
How do I prevent vitamin C deficiency in my guinea pig?
Offer fresh vegetables high in vitamin C daily — bell peppers (especially red and yellow) are excellent sources. Leafy greens like romaine, cilantro, and parsley are also good. Avoid relying solely on pellets for vitamin C, as it degrades quickly after the bag is opened. Vitamin C supplements can be added to water or given directly as drops.
Do guinea pigs need to live with other guinea pigs?
Guinea pigs are highly social animals and generally thrive with at least one companion. Solitary guinea pigs can become depressed and stressed. Same-sex pairs or groups work well. Introductions should be done carefully to avoid fighting. Dr. Davis can advise on bonding and group dynamics.
What should guinea pigs eat?
The foundation of a guinea pig diet is unlimited grass hay (timothy hay is ideal), which provides fiber for GI health and dental wear. Fresh vegetables (especially vitamin C-rich ones) should be offered daily. A small amount of high-quality guinea pig pellets can supplement the diet. Fruits should be minimal due to sugar content. Avoid foods high in oxalates (spinach, beet greens) in large quantities.
