Should I Get a Second Cat? It’s one of the most common questions cat owners ask themselves. Here’s what real owners wish they knew before bringing home a second feline.
They actually do keep each other company
This is the big one, and it’s not just feel-good talk. Indoor cats especially benefit from having a companion. According to International Cat Care, cats in multi-cat households show less stress-related behavior when they have a compatible buddy — less over-grooming, less destructive scratching, fewer signs of boredom. The Catster guide on pros and cons of two cats breaks this down in detail — the short version is that compatible pairs are genuinely healthier than solo indoor cats.
Kittens? Getting two is almost always better than one. They burn off energy on each other instead of using your curtains as a jungle gym.

You’ll see behaviors you never knew your cat had
Play-fighting, mutual grooming, sleeping in a pile — a lot of cats only show their full personality when another cat is around. The Cornell Feline Health Center notes that social play is a basic feline need that many single indoor cats simply can’t fulfill.
Less guilt when you leave the house
If you work long hours or travel occasionally, a second cat means your first cat isn’t sitting alone staring at the wall. The Pet Health Network confirms that for busy households, a compatible pair often does better than a single stressed cat.
The Cons Nobody Warns You About
Double everything — and I mean everything
Food. Litter. Vet bills. Insurance. Boarding. If your cat gets sick, you’re already paying. Two cats? That’s two of every bill. The ASPCA’s cat care guidelines are a good reality check on the real costs before you commit.
A second cat doesn’t just double your food bill — it doubles vet visits, litter costs, and emergency expenses for the next 15+ years.
The litter box math
The rule is one box per cat, plus one extra. Two cats = three litter boxes. Do you have space for three boxes? Because if you don’t, you’ll have peeing-outside-the-box problems fast. And that smell — two cats produce twice the waste, no way around it.
Personality clash is real
Not all cats want a friend. Some cats are genuinely solitary and will never accept another cat in their territory. The ASPCA has a whole section on inter-cat aggression, and it’s one of the most common behavioral issues they see. Forcing it doesn’t work — it makes things worse.
Why Some Owners Regret It
If you search “second cat regret” online, you’ll find hundreds of posts from owners who felt exactly like my friend — overwhelmed, guilty, and wondering if they ruined their first cat’s life. Here’s what they say, over and over:
- “My first cat changed completely.” A cat who used to sleep on your lap suddenly hides all day. That’s not them being dramatic — that’s fear. Your cat’s entire territory just got invaded. It takes time.
- “I rushed the introduction.” This is the number one mistake. Putting two cats in the same room on day one and hoping they’ll figure it out? That’s a recipe for inter-cat aggression that can last for years. The Chewy introduction guide recommends a process that can take weeks, not days.
- “Nobody told me it could take months.” Most resources say “give it a few days.” Reality? Some cats need 2-3 months before they’re comfortable sharing space. If you’re not prepared for that timeline, you’ll panic and think it’s failed.
The average successful cat introduction takes 2 to 6 weeks, but some pairs need up to 3 months before they’re fully comfortable.
How to Know If YOUR Cat Wants a Friend
Should I Get a Second Cat? Before you even think about heading to the shelter, ask yourself these questions:
Signs your cat might want company:
- They follow you around constantly and meow when you leave
- They’re under 2 years old (young cats adapt much faster)
- They’ve lived with other cats before and did fine
- They seem bored despite plenty of toys and playtime
Signs your cat does NOT want company:
- They’re 7+ years old and have been solo their whole life
- They hiss or growl when they see cats through the window
- They have medical issues that make them easily stressed
- Your home is small with limited hiding spots
The Whisker guide on two-cat households has a decent breakdown of compatibility factors, but the short version is: young, social cats do better with a friend. Older, set-in-their-ways cats often don’t.
The Right Way to Introduce a Second Cat
If you’ve decided to go for it, do NOT skip steps. The PetMD introduction guide and International Cat Care’s method both agree on the same basic process:
- Week 1: Separate rooms. The new cat stays in one room with their own food, water, and litter. Your resident cat keeps the rest of the house. They can smell each other under the door — that’s enough for now.
- Week 2: Scent swapping. Rub a towel on each cat and place it near the other’s food bowl. They start associating the other cat’s smell with good things. If either cat shows signs of stress, slow down.
- Week 3: Visual contact through a barrier. A baby gate, a cracked door — something where they can see but not touch. Short sessions, 10-15 minutes, with treats for both cats.
- Week 4+: Supervised time together. No forcing. If there’s hissing, separate them and go back a step. The Animal Foundation’s step-by-step introduction guide has a solid breakdown for this phase — introducing a kitten to an adult cat follows the same process, but kittens are usually more adaptable.

FAQ
Is it cruel to have just one cat?
No, and believing this is a dangerous mistake that pushes people into getting a second cat they’re not ready for. Plenty of single cats live perfectly happy lives with enough attention, play, and enrichment from their humans.
Will my cat be less lonely with a friend?
Maybe. Some cats genuinely benefit from a companion. Others see a new cat as an intruder. It depends on personality, age, and how well you handle the introduction.
How long does it take for two cats to get along?
Typically 2-6 weeks with proper introductions. Some pairs need months. A small percentage never become friends but learn to tolerate each other — and that’s okay too.
Should I get a kitten or an adult as my second cat?
Kittens are more adaptable and less threatening to a resident adult cat. But they’re also more energetic and annoying. An adult cat with a known calm temperament is often a safer bet for a smooth introduction.
What if they never get along?
It happens. Some cats coexist peacefully without being friends — they just stay in different zones. If there’s actual fighting (not just hissing), you may need to consult a vet behaviorist. But most pairs figure out a working relationship eventually.
