New Guinea Pig Owner Checklist (2026): Everything You Actually Need for Week 1

Bringing home guinea pigs is exciting… and a little overwhelming. Between cage sizes, bedding choices, and the “are they eating enough?” worry, it’s easy to overbuy the wrong stuff (and still miss the true essentials).

This beginner-friendly guinea pig checklist keeps it simple: what you need for week 1, what can wait, and how to set up your home so your guinea pigs settle in faster.

Quick note: Guinea pigs are social animals. In most cases, it’s best to start with a bonded pair (same-sex or properly paired) so they’re not lonely.

Quick answer: the week-1 essentials

If you want the short version, focus on these 8 things first:

1. A properly sized habitat for two guinea pigs

2. Paper bedding or fleece liners (plus a spot-clean routine)

3. Unlimited hay + a hay rack

4. Guinea pig pellets + daily vitamin C–rich veggies

5. Two water bottles (or a heavy bowl + backup)

6. Hideouts (at least two) + a cozy “base camp” layout

7. Chews + simple enrichment (tunnels, foraging)

8. Basic grooming + a small-animal vet plan

Before you bring them home: set up a calm “base camp” habitat

Guinea pigs do best when their world starts predictable. Set up the full habitat before they arrive so you’re not rearranging things while they’re stressed.

What to put in the habitat

• Bedding/liners + a simple “kitchen” area (hay + pellets + water)

• Hay rack with unlimited hay

• Pellet bowl

• Two water sources (two bottles is easiest)

• Two hideouts (one per pig)

• One tunnel or fleece forest

• A chew toy

Why this matters

A consistent layout helps them learn where food and water are, feel safe enough to eat, and start building trust. The #1 week‑1 goal is simple: calm + eating + routine.

New guinea pig owner checklist: what to buy (and why)

Here’s the full checklist, with “must-have now” vs “nice to have later.”

1) Habitat size + setup (must-have now)

You need

• A habitat that’s actually roomy for two guinea pigs

• A secure lid if you have other pets

• A solid floor (no wire floors)

Beginner tip

Bigger is almost always better. More space reduces stress and squabbles, and it encourages movement.

2) Bedding/liners + cleaning supplies (must-have now)

You need

• Paper bedding or fleece liners (with absorbent layer)

• A small broom/dustpan or handheld vacuum for daily spot-cleaning

• Pet-safe cleaner for the habitat base

Beginner tip

If odor is your worry, the solution is usually spot-cleaning + enough absorbency, not heavy perfumes.

3) Unlimited hay + hay rack (must-have now)

You need

• Unlimited grass hay (timothy/orchard/meadow)

• A hay rack or hay bag to keep it cleaner

Why it matters

Hay supports digestion and helps wear down teeth. It’s the foundation of guinea pig care.

4) Pellets + vitamin C foods (must-have now)

You need

• Guinea pig pellets (plain, not colorful mixes)

• Daily vitamin C–rich veggies (bell pepper is a common go-to)

Beginner tip

Guinea pigs need vitamin C in their diet. Keep it simple in week 1: introduce veggies gradually and watch their poop/behavior.

5) Water setup (must-have now)

You need

• Two water bottles (one per pig is ideal)

Beginner tip

Two bottles reduces competition and gives you a backup if one leaks or gets stuck.

6) Hideouts + comfort (must-have now)

You need

• At least two hideouts (so nobody gets “trapped out”)

• Soft fleece items (pads, forests) for cozy coverage

Beginner tip

Choose hideouts with two exits when possible—this helps prevent squabbles.

7) Chews + enrichment (must-have now, but keep it simple)

Start with a small variety:

• One tunnel

• A couple of chew-safe toys

• A simple foraging option (hay stuffed in a paper bag or cardboard tube)

Beginner tip

Week 1 is about comfort and confidence. You don’t need a toy mountain—just a few “safe and interesting” options.

8) Grooming + basic care + vet plan (must-have now)

You need

• Nail clippers (small animal)

• A soft brush (especially for long-haired breeds)

• A plan for a small-animal vet (exotics)

Beginner tip

If a guinea pig stops eating, seems puffed up, or is very quiet/lethargic, treat it as urgent and contact a vet.

What can wait until week 2–4 (don’t overbuy)

It’s tempting to “buy your anxiety.” These can wait until you learn your guinea pigs’ preferences:

• Extra hideouts and beds (start with two solid ones)

• Fancy treat assortments

• Big toy bundles

• Multiple cage upgrades (dial in the basics first)

• Smart tech add-ons (camera) if you’re still establishing routine

Common questions new guinea pig parents ask

Do I really need two guinea pigs?

In many cases, yes—guinea pigs are social and often do better with a companion. If you’re starting fresh, a bonded pair can reduce loneliness and stress.

What’s the biggest mistake beginners make?

Buying a habitat that’s too small and relying on “cute” pet-store mixes instead of the basics: space, hay, simple pellets, vitamin C foods, clean water, and hideouts.

How do I help them settle in faster?

Keep the environment quiet, avoid too much handling in the first couple days, and focus on routine. Sit nearby, talk softly, and offer veggies by hand once they’re eating confidently.

A simple week-1 setup plan (day by day)

Day 1: Quiet + safety

• Place them gently into the habitat

• Offer hay and water immediately

• Keep handling minimal

• Let them hide and observe

Day 2–3: Routine + trust

• Same feeding times

• Start offering a small amount of veggies daily

• Sit near the habitat and let them approach

Day 4–7: Build confidence

• Add one new enrichment item at a time (tunnel, foraging)

• Begin short, gentle handling sessions if they’re calm

• Keep spot-cleaning daily so the habitat stays fresh
