How much does a guinea pig cost per month? Detailed budget

🐹 Rodents · 🍖 Food · updated 2026-07-11

How much does a guinea pig cost per month? Expect 35 to 55 € per month for a pair (you never adopt a lone guinea pig), more than half of it going on food: unlimited hay, daily fresh vegetables and vitamin-enriched pellets. The right products are detailed in our rodent food category.

How big is the food budget?

It is the heart of the budget, because a guinea pig eats around the clock:

How much does upkeep cost (bedding and hygiene)?

For a 1.5 m² enclosure, plan 10 to 18 € of bedding per month depending on the setup — the full cost comparison is in our article on the true cost of bedding. Washable textiles (fleece liners) cut this item in half after an initial 40 to 60 € investment, in exchange for a little detergent and electricity.

Should you set aside a vet fund?

Yes, without fail. Guinea pigs hide their illnesses: dental abscesses, fungal infections and digestive trouble are common. Set aside 10 to 15 € per month in a dedicated account: an exotics vet consultation costs 35 to 60 €, dental work under anaesthesia 150 to 300 €. Spreading the cost avoids a financial dead end the day the animal — especially an ageing one — needs care; see our article on the ageing guinea pig.

How can you cut the bill without harming the animal?

Buy hay in bulk (10 kg bags), grow parsley and herbs in a planter, switch to washable liners and buy durable equipment second-hand. On the other hand, never skimp on fresh vegetables or hay: those are health items, not comfort items.

Frequently asked questions

What does the first year cost?

Setup (enclosure, accessories: 150 to 250 €) + adoption (30 to 60 € for a pair from a rescue) + the monthly budget: expect 600 to 900 € for the first year.

Does a guinea pig cost more than a hamster?

Yes, two to three times more: it lives in pairs, eats fresh vegetables daily and lives 5 to 8 years.

Is exotic pet health insurance worth it?

At 8 to 15 € per month per animal, a dedicated savings pot is often the better deal, except for fragile bloodlines.
