Why Preparation Matters More for Small Pets
Small pets — rabbits, guinea pigs, hamsters, gerbils, rats, birds, reptiles, and fish — are sometimes assumed to be low-effort companions. In practice, many have surprisingly specific needs, and the consequences of getting the basics wrong often show up quickly. Unlike dogs and cats, small animals frequently mask discomfort and illness until a problem is advanced, which makes good setup and daily observation especially important from the start.
This checklist is designed to be worked through before the animal comes home, not after. If you're setting up for a cat instead, see our room-by-room cat setup guide. For a new dog, the new dog owner checklist covers first-day essentials. This guide focuses on the small-pet household — where preparation is often the difference between a thriving animal and a stressful first month.
Not All Vets Treat Small and Exotic Animals
Many general veterinary practices do not see rabbits, reptiles, birds, or other exotic species — these animals require practitioners with specific training. Finding a qualified vet before your pet arrives, not in the middle of a health concern, is one of the most important steps on this list. Call ahead and confirm the practice has direct experience with your species.
What You'll Need
The specific tools vary by species, but most small pet setups draw on the same core categories. Gather these before arrival day.
Species-appropriate enclosure
Provides safe, correctly sized housing — cage dimensions, ventilation, and material requirements differ significantly between rabbits, hamsters, birds, and reptiles.
Bedding or substrate
Lines the enclosure floor to support natural behaviors like burrowing, absorb waste, and maintain hygiene — the correct type depends on species.
Food and water dispensers
Species-appropriate bowls, sipper bottles, or gravity feeders that keep food and water clean and accessible at all times.
Species-specific diet staples
Core food items — hay, pellets, seed mix, fresh produce, or live food — sourced before arrival so feeding can start correctly from day one.
Hiding spots or nesting material
Gives prey animals a place to retreat and feel secure, which is critical for reducing stress in the first days.
Thermometer or hygrometer
Monitors temperature and humidity inside or near the enclosure — essential for reptiles, birds, and some small mammals with narrow comfort ranges.
Carrier or travel container
Needed to bring the animal home safely and for any future vet visits — should be secure and ventilated.
Enrichment items
Tunnels, chews, foraging toys, or climbing structures that reduce boredom and support natural behaviour — see <a href="/pets-animals/small-pets-and-more/enrichment-ideas-that-keep-small-pets-mentally-active">enrichment ideas for small pets</a> for guidance.
The Pre-Arrival Checklist
Work through each group below. Items marked must are non-negotiable before the animal arrives. Should items are strongly recommended within the first week. Nice-to-have items improve quality of life over time.
Research and planning
Housing and environment
Diet and feeding
Health and vet preparation
Daily care and routine
Once your pet is settled, enrichment ideas for small animals can help you build on a strong foundation. And knowing the early signs that a small pet may be unwell is genuinely useful reading before your new companion arrives.
Small Animals Often Hide Illness Until It's Advanced
Prey animals — including rabbits, guinea pigs, hamsters, and many birds — instinctively conceal signs of weakness. By the time obvious symptoms appear, a condition may already be serious. Establishing a clear picture of your individual pet's normal appetite, weight, droppings, and activity level in the first days makes it far easier to spot something worth checking with a vet. When in doubt, consult a qualified exotic animal veterinarian promptly rather than waiting to see if things improve.
