🧬 Why Cats Struggle with Change
Cats are territorial and routine-oriented. Unlike pack animals, they rely heavily on scent, space, and predictability for comfort. Introducing a new pet disrupts:
-
🏠 Their territory (the home)
-
👃 Their scent environment
-
🕑 Their daily routine
📖 According to the American Association of Feline Practitioners (AAFP), sudden environmental changes are a major cause of feline stress, leading to behavioral issues, urinary problems, and aggression【Source: https://catvets.com/guidelines/practice-guidelines/environmental-needs】.
🟢 Step-by-Step Guide to Training Your Cat to Accept a New Pet
Step 1: Prepare Before Bringing the New Pet Home 🏡
-
Set up a separate room for the new pet with food, water, toys, and litter.
-
Keep your cat’s routine unchanged.
-
Buy pheromone diffusers (Feliway) to reduce feline stress.
-
Gather double sets of essentials (bowls, beds) to avoid resource guarding.
Step 2: Scent Introduction 👃
-
Rub a cloth on your new pet’s face, then place it near your cat’s favorite spots.
-
Do the reverse with your cat’s scent for the new pet.
-
Reward calm sniffing with treats.

Step 3: Controlled Visual Introduction 👀
-
Use a baby gate or cracked door so your cat can see the new pet without contact.
-
Keep sessions short (5–10 minutes).
-
Reward calm behavior with praise and treats.
Step 4: Supervised Face-to-Face Meeting 🐾
-
Put your cat on one side of the room, new pet on the other.
-
Keep dogs leashed; hold small pets in a carrier.
-
End session if hissing, growling, or swatting escalates.
-
Gradually increase time as tolerance improves.
Step 5: Shared Space Training 🛋️
-
Allow short, supervised time together.
-
Provide multiple escape routes for your cat.
-
Place resources (food, litter, toys) in different areas to reduce conflict.
Step 6: Long-Term Coexistence 🕑
-
Feed pets on opposite sides of a door, then closer together once calm.
-
Encourage play sessions with parallel toys.
-
Continue to reward peaceful interactions.
⏳ How long does it take?
-
Some cats adapt in 2–3 weeks.
-
Others may take months—especially older or single-cat households.
