Why Preparation Matters More with Small Pets

Small companion animals — rabbits, guinea pigs, birds, hamsters, and their kin — are often assumed to be low-maintenance alternatives to cats and dogs. In practice, many have highly specific environmental, dietary, and social needs that can be easy to overlook without deliberate preparation. A rabbit not provided with unlimited hay, or a guinea pig without a companion and sufficient space, can develop serious health and behavioural problems within weeks.

This checklist is designed to help you work through the four most critical preparation areas before your pet arrives: research and decision-making, veterinary access, housing, and home safety. If you are still weighing your options, our comparison of guinea pigs and rabbits can help you identify which species fits your lifestyle. For a sense of how small-pet preparation differs from bringing home a dog, see our guide to bringing a dog home for the first time.

Non-stick cookware fumes can kill birds

Polytetrafluoroethylene (PTFE), found in many non-stick coatings, releases odourless fumes when overheated that are rapidly fatal to pet birds. If you keep a bird, remove non-stick cookware from your kitchen or ensure the bird's living area is completely separated and thoroughly ventilated. Scented candles, air fresheners, and aerosol sprays pose similar respiratory risks.

Not all vets treat small exotic animals

Many general veterinary practices do not accept rabbits, guinea pigs, or birds as patients. Waiting until your pet is ill to search for a qualified vet wastes critical time. Call ahead, confirm the practice's experience with your species, and keep the clinic's emergency contact on hand from day one.

What You'll Need Before Day One

Having the right supplies in place — fully set up and tested — eliminates the stress of scrambling once your pet is already home. Use the tool list below as your shopping framework, then cross-reference with the species-specific notes in the checklist.

Required

Appropriately Sized Enclosure

Provides a safe, species-correct living space that supports natural behaviours and physical health.

Required

Paper-Based or Fleece Bedding

Creates a comfortable, low-irritant substrate for rabbits and guinea pigs; avoid cedar or pine.

Required

Heavy Ceramic Food Bowls and Water Bottle

Delivers stable, hygienic food and water access that resists tipping and is easy to sanitise.

Required

Species-Appropriate Enrichment Items

Reduces boredom and stress by encouraging natural foraging, chewing, or exploration behaviours.

Required

Vitamin C Supplement (guinea pigs only)

Prevents scurvy by supplementing a nutrient guinea pigs cannot produce on their own.

Optional

Small-Animal First Aid Reference

Helps owners recognise early illness signs and know when to seek immediate veterinary attention.

Housing setup deserves particular attention. Enclosure size is one of the most common places new owners underestimate their pet's needs. For a detailed breakdown of what guinea pigs specifically require, our guide to guinea pig housing, space, and bedding covers minimum dimensions, safe materials, and enrichment essentials.

The Complete Preparation Checklist

Work through each group below systematically. Items marked must are non-negotiable for your pet's health and safety. Should items are strongly recommended and will meaningfully improve your pet's welfare. Complete as many as possible before pick-up day.

Research & Decision-Making

Research the specific species you plan to adopt — rabbits, guinea pigs, and birds each have distinct dietary, social, and environmental needs that differ significantly from one another. Must
Confirm that every person in the household is comfortable with — and not allergic to — the species you are considering. Must
Assess your household's noise level and activity patterns, as some small animals (rabbits, guinea pigs) are easily stressed by loud environments, while some birds thrive with social stimulation. Should
Understand the animal's expected lifespan — rabbits and some parrots can live 10–15 years, requiring a long-term commitment. Must

Veterinary Care

Locate a veterinarian who is experienced with exotic or small animals before your pet comes home — not all general-practice vets treat rabbits, guinea pigs, or birds. Must
Schedule a new-pet wellness exam within the first week of arrival so a vet can establish a health baseline. Must
Ask the vet about species-appropriate parasite prevention, spaying or neutering (relevant for rabbits and guinea pigs), and any vaccinations applicable in your region. Should

Housing & Enclosure Setup

Purchase an enclosure that meets the minimum space requirements for your species — for guinea pigs, that generally means at least 7.5 square feet of floor space for one animal. Must
Set up the enclosure fully — including bedding, water, food dishes, hides, and enrichment — at least 24 hours before your pet arrives so everything can air out. Must
Place the enclosure in a location with stable temperature, away from direct sunlight, drafts, and kitchen cooking fumes (especially important for birds, whose respiratory systems are highly sensitive). Must
Choose appropriate bedding for your species — paper-based or fleece bedding for guinea pigs and rabbits; avoid cedar or pine shavings, which can irritate airways. Must
Provide species-specific enrichment: chew toys and tunnels for rabbits and guinea pigs; perches of varying diameters and foraging toys for birds. Should

Diet & Supplies

Stock the correct staple diet before your pet arrives — unlimited hay for rabbits and guinea pigs, a nutritionally complete pellet mix or species-appropriate seed blend for birds. Must
Learn which foods are toxic to your species — for example, onions, garlic, and avocado are dangerous to many small animals and birds. Must
Have fresh water available in an appropriate dispenser (bottle or heavy ceramic bowl depending on species) and check that it functions correctly. Must
Purchase vitamin C supplements if adopting guinea pigs, as they cannot synthesize this nutrient themselves and deficiency leads to serious illness. Must

Home Safety

Audit your home for toxic houseplants — many common plants, including pothos and peace lily, are dangerous to rabbits, guinea pigs, and birds. Must
Identify and secure any hazards in free-roam areas: exposed electrical cords, small gaps behind furniture, and open water sources. Must
Plan how you will safely separate existing cats or dogs from the new small pet during introductions and unsupervised periods. Should
If adopting a bird, eliminate non-stick cookware and scented candles from the bird's environment — fumes from these can be rapidly fatal. Must

Daily Care Planning

Write out a daily care schedule that includes feeding times, enclosure spot-cleaning, fresh water changes, and out-of-cage time or handling sessions. Should
Arrange reliable care coverage — a trusted pet sitter or boarding option — for travel or emergencies, and confirm they are comfortable with your species. Should
Set a realistic cleaning routine: guinea pig and rabbit enclosures typically require full bedding changes weekly and spot-cleaning daily. Must

Guinea pigs require daily vitamin C

Unlike most mammals, guinea pigs cannot synthesise vitamin C and must obtain it through diet every day. Deficiency causes scurvy, which leads to joint pain, lethargy, and can become life-threatening. Fresh leafy greens such as romaine lettuce and bell pepper are excellent dietary sources; discuss supplementation options with your exotic-animal veterinarian.

Once your small pet is settled in, understanding their social behaviour becomes the next priority. Guinea pigs, for instance, are social animals that generally do better in pairs, while hamsters are typically solitary. Our article on socialising small pets explains the social dynamics that work — and those that don't — across common species.
