# How long do cats live?

> Indoor pet cats often live 15–17 years; many reach their early twenties with good care. Outdoor and feral cats average shorter lives from traffic, disease and predation. Companion cats with regular veterinary care commonly live into their mid-teens; many reach early twenties.

## Key takeaways
- Indoor cats often 15–17+ years with vet care.
- Outdoor and feral cats average shorter lives.
- Neutering and TNR improve welfare and population stability.
- Obesity and dental disease shorten healthy years.
- Purring does not always mean happiness — context matters.
- Wild big cats face separate conservation threats.

## Answer
Neutering reduces roaming and fight injuries — extending lifespan. Vaccination and parasite control prevent common killers. Obesity and dental disease shorten lives when untreated.

Feral colonies managed through trap-neuter-return show improved health markers though outdoor risk remains. WARN rescue routes include community cat programmes where partners operate TNR ethically.

Record ages exceed 30 years in isolated cases — not typical. Breed matters less than for dogs though some purebreds carry inherited disorders.

## Indoor longevity factors
Vaccination against panleukopenia, calicivirus and rabies where required prevents early death. Parasite control for fleas and worms reduces anaemia and transmission. Indoor cats avoid cars and coyotes — primary mortality for suburban outdoor cats in US and Europe. Environmental enrichment reduces stress obesity from boredom — scratching posts and play mimic hunting. Annual veterinary exams catch hyperthyroidism and kidney disease common in geriatric cats — treatable when caught early.

## Feral and community cats
Unmanaged feral colonies reproduce rapidly — kitten mortality high from disease. TNR stabilises population and reduces fighting among sterilised adults. Colonies with caretaker feeding and shelter show better body condition — still shorter average life than indoor pets. WARN rescue routes include ethical cat programmes where partners document TNR outcomes — distinct from unsupported hoarding situations.

## Reading purr and pain
Cats purr when stressed or in pain — not only when happy. See why do cats purr answer — welfare assessment needs full body language. Elderly cats hide illness — weight loss and litter box changes signal vet visit. Quality of life decisions for geriatric cats balance extension with suffering — International Cat Care publishes end-of-life guidance.

## Wild felids contrast
Wild cats — lion, tiger, leopard — face poaching and habitat loss shortening lives regardless of veterinary access. Domestic cat longevity discussion separate from big cat conservation — but donor interest in cats can link to why big cats endangered answer and habitat appeals where appropriate.

## FAQ
### How long do indoor cats live?
Often 15–17 years; many reach twenties with good veterinary care.

### Do outdoor cats live shorter lives?
Yes on average — traffic, predators, fights and disease increase mortality.

### How long do feral cats live?
Variable — often several years with TNR and feeding; kitten mortality remains high.

### Does neutering help cats live longer?
Reduces roaming and fighting injuries; lowers risk of some reproductive cancers.

### Why do cats purr when dying?
Purring may self-soothe — not sign of comfort alone; see purr answer.

### What kills older cats?
Kidney disease, hyperthyroidism, cancer and dental disease — often manageable if caught early.
