Do cats get lonely? Some cats appear comfortable with periods of solitude, while others form strong social bonds with people or other cats and can show separation-related problems. Research supports feline attachment and social contact, but it does not support a rule that every cat needs another cat for company (Vitale et al., 2019; Eriksson et al., 2017; FelineVMA, 2025).

Do Cats Get Lonely? What Research Actually Shows
Cats have flexible social behavior. Merck describes cats as capable of living alone or in social groups depending on resources and individual history (Merck Veterinary Manual, updated 2025). In a 2019 Current Biology study, cats showed distinct attachment patterns toward human caregivers. That finding supports social bonds, but attachment is not identical to loneliness.
A small 2017 home study followed 14 single-housed cats during 30-minute and four-hour owner absences. The cats did not show clear behavioral differences during the two separation periods, but after the longer absence they purred and stretched more at reunion. The authors interpreted this as increased contact-seeking after a longer separation, not proof that the cats suffered while alone (Eriksson et al., 2017).
| Claim | Evidence | Better conclusion |
|---|---|---|
| Cats are totally solitary | Cats can form social bonds | Too simple |
| Every cat needs a second cat | Individual social preferences differ | Not supported |
| Owners can matter socially | Attachment and reunion studies support this | Supported with limits |
| Any meowing means loneliness | Many medical and behavior causes exist | Needs context |
Do Cats Get Lonely When Left Alone?
Do cats get lonely when left alone cannot be answered from one behavior. A 2020 questionnaire study of 223 cats found that 30 cats met at least one author-defined criterion for separation-related problems. The study was exploratory and owner-reported, so it does not establish a population prevalence rate or diagnose individual cats (de Souza Machado et al., 2020).
Instead, look for patterns that happen specifically around departures or absences. Sudden house-soiling, destructive behavior, marked vocalization, agitation, or overgrooming deserves context and, when new or intense, medical evaluation. The stressed-cat guide and sudden-hiding guide explain why behavior changes should not automatically be labeled emotional. For a related behavior guide, see why Cats Meow at Their Owners.
- Provide a safe place where the cat can retreat without being disturbed.
- Offer play and predatory-style activities that fit the individual cat.
- Keep human interaction positive, consistent, and predictable.
- Place key resources so the cat can use them without conflict.
- Watch what the individual cat chooses rather than assuming every cat wants constant contact.
FelineVMA lists positive, predictable human-cat interaction as one pillar of a healthy indoor environment (FelineVMA, 2025). That makes social contact important, but not identical for every cat. The indoor-cat boredom guide, calm-space guide, and slow-blink article cover enrichment and low-pressure interaction.
So, do cats get lonely in the same way and under the same conditions? Current evidence says their social responses vary, which is why the individual pattern matters more than a universal label.
Does a Lonely Cat Need Another Cat?
A second cat is not a universal treatment for loneliness. Feline social compatibility varies, and FelineVMA guidance emphasizes that each cat needs safe access to key resources. If you plan to add another cat, use the two-cat introduction guide rather than putting unfamiliar cats together immediately. For mixed-species homes, use help pets get along.
If the cat already lives with companions, watch for subtle tension as well as friendly contact. Separate food, water, litter, rest, hiding, and scratching resources when needed. The daily cat care checklist and weekly pet care checklist make it easier to notice changes in routines.
When owners ask do cats get lonely, the useful follow-up is what changed, when it happens, and whether the cat is otherwise healthy. That approach separates a social question from a possible medical problem.
When to Call Your Vet
New withdrawal, appetite loss, overgrooming, house-soiling, pain signs, or a major change in social behavior can have medical as well as behavioral causes. Call your veterinarian rather than assuming loneliness. Use pet emergency signs if the cat is acutely ill or cannot urinate.

Do Cats Get Lonely FAQ
No. Individual cats differ, and current research does not support one universal response to being alone.
Yes. Attachment studies show that cats can form distinct attachment relationships with human caregivers.
Not automatically. Some cats enjoy compatible feline companions, while others prefer more distance. A second cat can also create tension.
No. Vocalization has many possible causes. Look for a consistent separation pattern and rule out health problems when behavior changes.
FelineVMA recommends positive, consistent, predictable human-cat interaction as part of a healthy feline environment, tailored to the individual cat.
