27 Oct Should You Get a Second Cat? A Practical Checklist
Updated 9 October 2026 · Cat Tree UK editorial team
A second cat can be a welcome addition to the household, but it is not automatically a companion your current cat wants. Some cats form close relationships; others find sharing difficult. Make the decision around both animals’ needs rather than assuming two cats always keep each other entertained.
Consider the cat you already have
Think about their history with other cats, age, health and response to change. Living peacefully with one familiar cat in the past does not prove that any new arrival will be welcome. Equally, a breed label cannot predict a particular relationship.
Talk to the rescue about the prospective cat’s known preferences and previous living arrangements. Avoid choosing on appearance alone or relying on labels such as alpha and beta to promise a match.
Check space and resources
Can you initially provide a separate room with the new cat’s own essentials? Later, both cats need access to food, water, litter trays, scratching areas, hiding places and resting spots without being blocked by the other.
Multiple resources crowded into one corner are not equivalent to options distributed around the home. Assess routes through doorways and narrow spaces, as well as the number of bowls or beds. Our cat tree benefits guide explains why several beds on one tower do not prevent competition.
Budget for two individuals
Allow for ongoing food, litter, routine care, unexpected veterinary costs and holiday arrangements. One cat’s dietary or medical needs may differ from the other’s. Consider whether you have time to observe and support a gradual introduction rather than expecting immediate access to the whole home.
Introduce gradually
Begin with separate accommodation and follow a carefully paced introduction plan. Familiar scent exchange and controlled stages can help, but progress should depend on the cats’ comfort. Do not put them face to face and expect them to sort it out.
Step back if either cat is distressed. Ask the rescue, your vet or an appropriately qualified feline behaviour professional for help with persistent tension. A successful outcome may involve calm coexistence rather than shared sleeping or play.
When waiting is a sensible decision
It may be better to postpone if your cat is unwell, your household is changing substantially or you cannot provide separate space. If boredom is the concern, first improve play, choice and the existing environment. Another cat is a long-term responsibility, not an enrichment accessory.
Before committing, agree with the rescue how it supports introductions and what happens if the match cannot meet both cats’ needs.
