$100–$300/yr

Annual exotic vet wellness check. Dental checks are particularly important.

$200–$3,000

GI stasis, respiratory infections, and dental malocclusion are the most common serious conditions. Dental surgery can reach $1000-3000.

These are the costs that catch new Guinea Pig owners off guard. Budget for them from day one.

Vitamin C is non-negotiable Guinea pigs develop scurvy without daily Vitamin C. Fresh bell pepper is the cheapest source (~$1-2/week).

Fleece laundry costs Fleece liners need washing 1-2x/week — factor in water and electricity costs.

Bonded pair requirement Single guinea pigs require significantly more human interaction time or will suffer psychologically.

Hay volume Two guinea pigs consume hay surprisingly fast. Bulk hay purchases are significantly cheaper per unit.

Dental disease risk Malocclusion affects a significant % of guinea pigs over age 3. Budget $500+ reserve by year 2.
