Preparation before bringing kitten home

Set up a separate space

Prepare a quiet room for your kitten with food, water, toys, a bed, and a litter tray. This gives them a safe base.

Litter trays & resources

Ensure there are enough litter trays: one per cat plus one extra, all in separate, quiet locations.

Health check first

Get your kitten checked by a vet and keep them separate until vaccinations and parasite treatments are done.

Keep older cat’s routine stable

Maintain feeding and play schedules to minimise stress for your resident cat.

The first introduction

First meetings should be calm and brief. Let both cats see each other through a barrier, like a baby gate or cracked door, while you supervise. Reward calm behaviour with treats.

Scent swapping techniques

Why scent matters

Cats rely heavily on scent. Swapping bedding or gently rubbing a cloth on each cat and placing it near the other helps them get used to new smells.

Calming products

Use feline pheromone diffusers like Feliway in shared spaces to reduce tension during introductions.

Gradual introduction steps

Stage What to do
Stage 1 Keep cats separate, swap scents between them.
Stage 2 Allow visual meetings through a barrier, reward calm behaviour.
Stage 3 Short, supervised sessions together in neutral space.
Stage 4 Gradually increase time together, still supervise closely.
Stage 5 Allow free interaction when both cats seem relaxed and confident.

FAQs

How long does it take for cats to get along?
It varies by personality. Some pairs settle in days, others take weeks or even months. Go at their pace and don’t rush it.
What if my older cat hisses or growls?
Hissing is normal at first. Pause introductions, swap scents again, and give them more time apart before retrying.
Should I separate food and litter areas?
Yes, each cat needs their own resources in separate areas to prevent competition and reduce stress.
