Two guinea pigs beside hay and two hiding places

How much does a guinea pig cost? A budget for two guinea pigs

The cost of a guinea pig is more than just the price of the animal. When planning a home for two guinea pigs, calculate start-up costs, monthly purchases, and veterinary care separately. There is no single fair amount that applies to everyone: prices depend on location, how the animals are kept, and their health. Below, you’ll find sample prices in PLN checked on September 24, 2026, along with a formula for working out your own budget.

Why calculate the costs for two guinea pigs?

Guinea pigs need the company of their own species. Buying just one guinea pig to lower the bill is not a good plan. The RSPCA recommends keeping them with at least one compatible guinea pig, unless a specialist advises otherwise. Consider adopting an already bonded pair and check the adoption requirements before making a decision. You can read more about relationships between animals in the article about the social nature of guinea pigs.

How much does a guinea pig cost to get started?

The adoption fee or price of the animals is only one item. Before they arrive, prepare suitable housing and everyday supplies. Don’t assume a small cage will be enough at first: replacing it means another expense and an unnecessary restriction on space.

  • Two guinea pigs: check the adoption requirements or the animals’ background; make sure the pair is compatible and that unplanned breeding will not occur.
  • Housing and playpen: price suitable space, safe flooring, and protective barriers; you’ll find the selection criteria in the guide about guinea pig cages.
  • Supplies: hiding places for both guinea pigs, a place for hay, bowls or a water bottle, suitable bedding, and a carrier; the guinea pig starter checklist.
  • Initial supplies: hay, pellets intended for guinea pigs, and fresh vegetables.
  • Care plan: check the availability of a veterinarian who treats guinea pigs and ask the clinic for its price list for appointments and diagnostics.

What does it cost each month?

First, note how much of each product your animals actually use, then compare prices per unit, not just per package. Hay should always be available, as should fresh water. A daily diet also includes suitable fresh greens and guinea pig pellets; the guide explains the details what guinea pigs eat.

  • Hay: calculate how many packages you use; allow for hay wasted when it gets soiled during foraging.
  • Vegetables and pellets: estimate the amounts you actually buy and check freshness; don’t replace hay with a cheaper mix.
  • Bedding and hygiene: record how often you replace the bedding or the cost of washing liners, as well as animal-safe cleaning products.
  • Wear and tear on supplies: spread the cost of replacing worn hiding places or accessories over several months.

Don’t add unnecessary gadgets to your basic budget as a substitute for space or care. Regularly cleaning the housing and removing wet bedding are part of daily care, not a one-off purchase.

Sample product prices in PLN

The listed prices at zooplus, checked on September 24, 2026, apply to specific package sizes, not to monthly consumption guidelines for two guinea pigs. They may change; check the product option and delivery before buying.

One pack of each of these three products cost a total of 25 PLN (10.17 + 39.96 + 16.12 PLN). This is an example basket, not the monthly cost of keeping a pair: packs last for different lengths of time, and the basket does not include vegetables, other supplies or veterinary visits. To compare monthly expenses, multiply the price of a pack by the number of packs actually used in a month.

How do you calculate an annual budget for two guinea pigs?

Record the listings, dates and prices for your area. Check the prices of visits separately with a veterinarian who treats guinea pigs. There is no reliable fixed amount for a sudden illness: set aside an emergency fund that is available straight away, not only after saving for several months.

  1. Start-up: cost of the pair + housing + equipment + initial supplies.
  2. Monthly: hay + vegetables + guinea pig pellets + bedding/laundry + replacement of worn-out items.
  3. First year: Initial costs + later monthly purchases (without counting the initial supplies again) + planned visits and examinations. Keep an emergency treatment reserve separate: this is available funds, not an expense paid upfront.

In subsequent years, subtract one-off purchases, but include repairs or replacement of equipment. This calculation better reflects the actual costs than the animals’ price alone. When comparing offers, note the package size, delivery cost and date: without this information, an apparently cheap offer may turn out to be more expensive. You can find more about daily responsibilities in the guide to caring for guinea pigs.

Is it safe to save money?

Compare the price of hay and bedding for the same quantity, plan fresh vegetable shopping alongside other household shopping, and choose hides that are durable and easy to clean. Do not save money at the expense of hay quality, space, companionship or a vet visit. The RSPCA recommends checking your guinea pigs’ health daily and having a veterinary check-up at least once a year. If a guinea pig stops eating or produces fewer droppings, contact a vet immediately; do not wait until you have saved the planned amount.

Frequently asked questions about the cost of guinea pigs

Is adoption free?

Don’t assume so. The organization may have its own requirements and charge a fee; check directly with them. Even if there is no fee for the animals, you still have to pay for housing, food and care.

Do two guinea pigs cost exactly twice as much as one?

No. Some equipment is shared, but both guinea pigs eat and both may need treatment. So plan your budget for the actual number of animals, rather than automatically multiplying one arbitrary price.
