Why the Introduction Period Matters

The first days and weeks in a new home are the most formative period in a pet's life with you. Everything is unfamiliar — the smells, the sounds, the people, the routines. How you manage this transition shapes how secure and confident your pet will become.

Before Your New Pet Arrives

Set Up a Safe Zone

Choose a single quiet room as your new pet's base for the first few days. Equip it with a bed, water, food bowls, a litter tray if it's a cat, or a crate with soft bedding if it's a dog. This gives your new pet a controlled environment to decompress before exploring the wider home.

Pet-Proof the Space

Check for loose wires, toxic plants, small objects that could be swallowed, and unsecured bins. The RSPCA publishes species-specific guides to household hazards worth reading before your pet arrives.

The First 24-48 Hours

Keep the environment as calm as possible. Limit visitors, keep noise levels low, and resist the urge to handle your new pet constantly. Allow them to come to you rather than approaching repeatedly. Sit quietly in their space and let curiosity do its work.

Introducing a New Pet to Existing Pets

Dog to Dog

Introduce on neutral territory first — a park rather than your home. Keep both dogs on leads and walk parallel before allowing them to sniff. Watch for relaxed body language: loose posture, relaxed tail. Be cautious if you see stiff bodies or hard stares.

Dog to Cat

Keep the dog on a lead for all initial encounters. Feed both animals near the barrier of the safe room door so they associate each other's smell with positive experiences before meeting face to face.

Cat to Cat

Scent-swapping before visual introduction is crucial. Swap bedding between cats for three to five days before any visual contact. Use a slightly open door for the first visual introduction, with both cats able to retreat freely.

Introducing a New Pet to Children

Teach children to approach calmly, let the pet come to them, and never disturb a sleeping or eating pet. Young children should always be supervised. Set clear household rules: no chasing, no picking up without permission.

Signs the Transition Is Going Well

Your new pet is settling in if they're eating and drinking normally, beginning to explore independently, making eye contact, and showing relaxed body posture. With cats, purring and kneading are positive signs. With dogs, approaching for affection indicates growing comfort.

When to Ask for Professional Help

Persistent hiding for more than a week, refusal to eat for more than 48 hours, or aggression toward people or existing pets all warrant a vet conversation. For more pet guides, visit our Pet Care section.

Frequently Asked Questions

How long does it take a new pet to settle in?

The "3-3-3 rule" suggests three days to decompress, three weeks to learn the routine, and three months to feel truly at home. Some pets settle faster, others slower.

Should I let my new puppy sleep in my bedroom?

Wherever you start is where your dog will expect to sleep long-term. Decide before they arrive and be consistent from the first night.

My new cat won't eat. Is this normal?

It's normal for a cat to eat very little in the first 24-48 hours due to stress. If they haven't eaten after 48 hours, contact your vet as cats can develop hepatic lipidosis from prolonged food refusal.

Can I leave a new puppy alone on the first day?

Try to take a few days off work. Puppies need frequent reassurance and toilet trips, and a stressful first experience of being alone can contribute to separation anxiety.

Is it normal for my resident dog to growl at the new pet?

Some growling during introductions is normal. It becomes a concern if it escalates to snapping or biting, or if one animal cannot relax even when separated.
