June is Adopt a Cat Month, a time to raise awareness about the thousands of cats in shelters waiting for their forever homes. If you’re thinking about adopting, you may have heard of the 3-3-3 rule, a simple way to understand what your new cat experiences in their first days, weeks, and months in your home.

At Encore, we believe every adopted cat deserves patience, love, and the right support. Here’s how the 3-3-3 rule can help you set realistic expectations and ensure a smooth transition for your new feline friend.

What is the 3-3-3 rule?

The 3-3-3 rule represents the common stages of a newly adopted cat’s adjustment period:

  • 3 Days: Feeling overwhelmed
  • 3 Weeks: Settling In
  • 3 Months: Feeling at home

Every cat adjusts at their own pace, but this guide gives you a better understanding of their journey and how you can support them.

How long does it take a rescue cat to settle?

The first 3 days: overwhelmed & unsure

In the first few days, your cat is likely nervous, unsure, and possibly hiding.

  • May refuse food or the litter box
  • Might hide under furniture or avoid contact
  • Could be quiet, anxious, or even a little scared

How to help:

  • Give them a quiet space with a litter tray, food, and water.
  • Avoid overwhelming them with too much attention, let them come to you.
  • Stick to a consistent routine to help them feel secure.

Top tip: Even the friendliest cats may need time to adjust, patience is key!

The first 3 weeks: settling in & exploring

After about three weeks, your cat will start to feel more comfortable in their new home.

  • Exploring their surroundings
  • Developing a routine with meals & playtime
  • Showing more personality, may start seeking attention or playing

How to help:

  • Introduce new rooms gradually so they don’t feel overwhelmed.
  • Start bonding through play, interactive toys help build trust.
  • Encourage socialisation but respect their boundaries.

Top tip: If your cat is still very withdrawn or hiding after 3 weeks, consult your vet or a cat behaviourist for advice.

The first 3 months: Feeling at home

By 3 months, most cats feel comfortable, confident, and truly part of the family.

  • Fully adjusted to their routine
  • Bonding with their humans
  • Showing affection and trust

How to help:

  • Stick to a steady routine for food, litter cleaning, and play.
  • Continue to build trust, every cat bonds at their own pace.
  • Encourage enrichment, cat trees, scratching posts, and puzzle feeders keep them happy.

The 3-3-3 rule is a great guide, but remember, every cat is unique. Some settle in faster, while others take longer. The most important thing? Patience, love, and a safe space for them to grow.
