How to introduce two cats + resources needed
Resources needed (per type): 3 eachCalculated
2 cats + 1 = 3 of each: litter boxes, water bowls, food bowls, beds / resting spots, scratching posts — spread out so one cat can't guard them all.
Your plan
Introduction steps: 1) Separate rooms. 2) Swap bedding/scent daily. 3) Rub a cloth on each cat's cheeks and place near the other. 4) Play/feed on opposite sides of a closed door. 5) Brief visual contact through a cracked door/gate. 6) Short supervised sessions, extend only if calm.Fact
Pace: Move to the next step only when both cats are relaxed. Hissing that fades is normal; go slower if it doesn't. Never punish either cat.Fact
Watch for these
- Injurious fighting, or a cat so stressed it stops eating or using the box, needs a vet or behaviourist — do not let cats 'fight it out'.
Monitor with red flags. Watch for the specific red flags listed and escalate if they appear.
