Getting Ready for Your Critter

What You'll Learn in This Guide

• Critter-proofing your home
• Buying the essential supplies you need
• Introducing your critter to their new home

Before bringing your small animal home, preparation is key. Whether you plan to give your furry friend free time outside their cage—which most small animals need for optimal physical and mental health—or keep them secure in a habitat, pet-proofing is essential. You'll need to choose an enclosure that suits both your pet and your lifestyle, and stock up on food, treats, toys, and grooming supplies before their big arrival.

By preparing for safe introductions and anticipating adjustment challenges, welcoming your new companion will be much smoother. In this guide, we'll cover everything from crucial safety considerations to introducing your pocket pet to the entire family.

Preparing Your Home for a Small Pet

Small animals have an incredible knack for squeezing into dangerous places. Before you bring them home, ensure your living space is completely secure. Be vigilant about checking for holes in walls, gaps around pipes, open heating vents, or any dark spaces that naturally attract animals that love to burrow, tunnel, and hide.

Because these pets are naturally curious, they love exploring, foraging, chewing, and sneaking into furniture. Without proper supervision, they can easily get lost, injured, or poisoned. Even if you don't intend to let them roam freely, accidents happen. It's always best to secure the premises just in case.

Making Your Home Completely Critter-Proof

Critter-proofing the rooms where your pet will live or play requires a few vital precautions:

• Patch, fill, or block all holes in walls, floors, or pathways leading outside. If a hole can fit their skull, they can squeeze right through it.
• Tape, cover, or hide all exposed electrical cords to prevent dangerous chewing.
• Relocate furniture with moving parts (like recliners, rocking chairs, or sleeper sofas) where small animals could easily get trapped.
• Move easily chewable objects off the floor.
• Select a room with easy-to-clean flooring for their free-roaming playtime.
• Keep your critter’s cage well out of reach from other pets (like cats and dogs) who might instinctively view them as a meal rather than a friend.
• Place the cage away from direct sunlight and chilly drafts. Keep the room at a comfortable 65 to 75°F (18 to 24°C) to prevent heatstroke.

Should You Let Them Roam Free?

Free-roaming is a highly debated topic among pet owners. Some dedicate entire rooms to their pets, providing cages as safe havens with open doors. Ferrets, rabbits, rats, and guinea pigs commonly enjoy this setup, as they desperately need time outside their cages to stretch their legs, explore, and interact with you.

However, allowing them to roam completely unsupervised 24/7 is generally a bad idea. They can:

• Easily get lost or stuck in tiny crevices.
• Quickly destroy carpets, moldings, or drywall (rats and rabbits are notorious chewers).
• Leave waste everywhere, which makes cleaning a nightmare. (Though ferrets and rabbits can often be litter-trained!)
• Sustain serious injuries from being accidentally stepped on or sat on.

Pro Tip: In almost every case, your pet is safest living in a roomy, clean enclosure, supplemented with daily, heavily supervised free time outside the cage.

For quick, tiny pets like hamsters and mice, an exercise ball is a secure alternative when they aren't being actively held. These plastic spheres let them run and explore without getting lost or destroying your home.

Warning: Never allow a pet in a rolling exercise ball near stairs, open doors, or predatory pets like dogs or cats. Always monitor their time inside—limit it to no more than an hour so they don't get trapped without food or water.

Stocking Up on Crucial Supplies

Before bringing your tiny friend home, visit your local pet store to gather necessary supplies. Take your time to compare enclosures, find high-quality foods, and pick out engaging exercise equipment.

Choosing the Perfect Enclosure

Your pet's habitat will be your most important—and likely most expensive—purchase. A spacious, well-ventilated home with a solid floor is usually ideal. Prioritize maximum space and ease of cleaning.

Always aim for the largest enclosure you can afford. Most small animals need space to burrow and tunnel, and you'll need to clean it thoroughly at least once a week for their ongoing health.

• Ferrets: Need spacious wire cages (at least 24 x 24 x 18 inches). Avoid glass tanks due to poor ventilation. Provide hammocks, nesting rags, toys, PVC tubes for tunneling, and a litter box.
• Rabbits: Require a large wire cage (minimum 24 x 24 x 48 inches), preferably with a solid floor or a solid mat over wire to prevent painful foot infections. Provide litter boxes filled with recycled paper.
• Rats: Highly active and need vertical climbing space. A single rat needs a minimum of 24 x 24 x 24 inches, plus an extra square foot per additional rat.
• Guinea Pigs: Need solid flooring (at least 24 x 24 x 24 inches per pig). They don't climb much but love burrowing and exploring spacious, single-level areas.
• Hamsters, Gerbils, & Mice: Require escape-proof, well-ventilated wire cages or glass tanks with secure wire mesh lids. A 10-gallon tank is the absolute minimum for two gerbils or mice. Note: Golden hamsters are highly solitary and must live alone, while dwarf hamsters, gerbils, and mice thrive in same-sex pairs.
• Exotic Critters: Hedgehogs need a minimum 20-gallon glass tank with a secure lid to prevent climbing escapes. Chinchillas require tall, vertical wire cages (at least 2 x 2 x 3 feet) with solid floors and elevated nesting boxes.

Litter Training Tip: Ferrets naturally use corners, so place their litter box in the corner of their cage using recycled paper or wood pellets. Avoid clay cat litter, which harms their respiratory system. For more on this, check out our guide on Critter Behavior and Training.

Enclosure Rule of Thumb: If using a wire cage, ensure the bar spacing is narrow enough to prevent squeezing escapes. For glass aquariums, always purchase a tight-fitting, secure wire lid.

Getting the Right Accessories

Every small animal requires a few fundamental accessories for a happy, healthy life:

• Bedding: Opt for recycled paper, aspen shavings, or grass pellets. Never use pine or cedar shavings, as the natural phenols can severely damage small respiratory systems.
• High-Quality Food: Stick to species-specific diets. You can learn more about proper nutritional needs in our article about Taking Charge of Your Critter’s Care.
• A Heavy Ceramic Bowl: These prevent tipping, allowing your pet to rest on the rim comfortably while eating without making a mess.
• A Water Bottle: A side-mounted bottle with a metal ball nozzle keeps water clean from litter and waste. Remember to provide fresh water daily and thoroughly clean the bottle every few days.
• Food Supplements: Some pets need daily extras, like Vitamin C for guinea pigs. Read more in Taking Charge of Your Critter’s Care.
• Exercise Equipment: Keep them active with ladders, ropes, and a quiet running wheel (essential for hamsters, mice, and gerbils).
• Shelters and Tunnels: Provide hiding spots using store-bought shelters, cardboard boxes, PVC pipes, and clean nesting materials like shredded paper towels.

Don't Forget: If you're litter-training a ferret or rabbit, get boxes with low entry points and high backs. Also, if you plan to harness-walk your pet, a secure fit with a small bell helps you keep track of their whereabouts during free-roaming.

Helping Your New Critter Settle In

Moving is stressful for everyone, especially a tiny animal entering a completely alien environment. Give them the grace, quiet, and time they need to adjust comfortably to their new world.

Understand the Limits of Handling

While handling builds a strong bond, take it easy for the first couple of days. Let them explore, test their water bottle, and catch up on sleep. By the second day, you can try short, gentle handling sessions. Keep in mind that many small pets are nocturnal or crepuscular, meaning they are most active in the evening. Never wake a sleeping pet—it causes unnecessary stress and might result in a defensive nip.

Give Them Plenty of Space

If your pet seems overwhelmed by loud noises, children, or other pets, move them to a quieter, low-stimulus room. Introduce them to family members slowly over a week. Supervise any out-of-cage exploration closely.

Some pets, like ferrets and rabbits, may hide at first, while others might be ready to play immediately. Respect their individual pace and keep them securely caged when unsupervised until everyone settles into a reliable routine.

Supervise Your Children

Always closely monitor interactions between young children and new pets until you are completely confident your child understands how to handle the animal gently and responsibly.

Remember: An adult is ultimately responsible for a small animal’s health and daily care, even if the pet technically belongs to a child.

Know When to Back Off—And When to Get Help

If you're providing a calm environment but your pet is visibly struggling to adjust, watch for warning signs. Consult a veterinarian immediately if your pet is:

• Refusing to eat or drink
• Panting constantly or acting severely stressed
• Highly aggressive or constantly trying to bite
• Refusing to let you touch them at all after ample adjustment time

If they have a clean bill of health, they may just need more time. Rescued animals, in particular, might not be used to human touch. Be incredibly patient. With gentle handling and plenty of space, most critters will eventually learn to trust and interact with you.
