Adopting a Second Cat

Thinking about adopting a second cat?

Benefits of Having Two Cats

  • Companionship & Mental Stimulation
    Cats can keep each other company, play together, groom each other, and generally be less lonely, especially indoor cats.
  • More Exercise & Activity
    They can chase, wrestle, explore together — which can help burn off energy and reduce destructive behaviors.
  • Reduced Behavioral Issues
    Boredom often leads to behaviours like scratching furniture, excessive meowing, or seeking attention at night. A second cat helps distribute the “attention demand” and can reduce these issues.

Things to Consider / Potential Downsides

  • Personality & Temperament of Your Current Cat
    If your cat is very territorial, anxious, or has never had to share space, introducing a newcomer might be stressful.
  • Age Compatibility
    Introducing a young cat (kitten) to a kitten or young cat works more easily. An older cat may have more entrenched routines and territory.
  • Financial / Time Commitments
    Two cats mean more food, litter, vet care, space, toys, etc. Make sure you can support that.
  • Space & Resources
    Enough room, enough hiding spots, multiple feeding stations, litter boxes, scratching posts, etc. If resources are scarce or shared too closely, tensions can arise.

How to Prepare Before Bringing the New Cat Home

  • Safe / Separate Space
    Have a separate room (“sanctuary room”) for the new cat with its own litter box, food, water, bedding, hiding places. This allows them to settle in without being immediately confronted by the resident cat.
  • Supplies
    Enough litter boxes (one per cat + one extra), food bowls, scratching posts, hiding spots, etc.
  • Health Checks
    Make sure the new cat is vaccinated, spayed/neutered (or understand behavioral implications if not), free from parasites and disease. This protects both cats.

How to Introduce Them (Step-by-Step)

  • Scent Introduction
    Let them smell each other before they meet. Swap bedding, use cloths/towels rubbed on each cat to carry scent. Feed them on either side of a closed door so they associate the scent and sound of the other cat with something positive.
  • Controlled Visual Introduction
    After a few days of scent swapping, allow them to see each other through a barrier (baby gate, cracked door, screen) so they can observe without direct contact.
  • Short, Supervised Interactions
    Once visual introductions are calming (less hissing or growling), allow them short face‑to‑face meetings under supervision. Have toys or treats, be ready to separate if needed.
  • Gradual Increase in Interaction
    Slowly increase the time they spend together. Watch body language carefully. Retreat backwards if signs of stress escalate.
  • Full Integration
    Once they are tolerated, you can allow unsupervised time together, but continue to ensure each cat has escape options and their own safe spaces. Vertical space (cat trees, shelves) helps.

Signs Things are Going Well vs. Red Flags

Good signs:
  • Cats grooming themselves and/or each other.
  • Sharing space without conflict Eating, drinking, playing in the same room.
  • Relaxed body language (tail upright or relaxed, ears forward or neutral).
Warning signs:
  • Persistent hissing, growling, fighting.
  • One cat hiding a lot or refusing to go to food or litter box.
  • Changes in eating/drinking, bathroom habits.
  • Stress behaviours (overgrooming, aggression).
If warning signs occur, back up a step in the introduction process or consult a vet or behaviorist.
