Short direct answer
Cats typically mourn the loss of another cat for a few days to several months, depending on their bond and personality. Most cats show signs of grief like searching or withdrawal, but they usually return to normal behavior within six months, moving through stages of active searching, passive depression, and eventual acceptance.
Losing a feline companion hits hard for pet owners like you in the USA, where cats are family members. It can leave your surviving cat confused and sad, affecting their health and your bond. Understanding feline grief helps you support them through this tough time, preventing bigger issues and strengthening your relationship.
Understanding Cat Grief
Cats form deep bonds with other cats, especially if they’ve lived together long-term. When one passes, the survivor may grieve due to the sudden change in their social world. This isn’t just imagination studies and vet observations confirm it.
Do Cats Really Mourn?
Yes, cats experience grief, though it’s different from humans. They don’t understand death permanently, but they notice the absence. A survey by the ASPCA found that cats often change behaviors after losing a companion, like eating less or vocalizing more. Real-life examples include cats pacing rooms or sniffing spots where the other cat slept.

Not all cats grieve the same. Some show no signs if the bond was weak, while closely bonded pairs like littermates may react strongly. Vets note that outdoor cats might grieve less visibly than indoor ones reliant on companions.
Factors Influencing How Long Cats Mourn
The mourning period varies widely. Key factors include:
- Bond Strength: If the cats were inseparable, playing and grooming together, grief can last longer up to months. For casual housemates, it might be days or none at all.
- Age and Health: Older cats or those with health issues may grieve harder, as the loss adds stress. Kittens adapt faster.
- Environment Changes: Moving routines or homes during grief prolongs it. Stable homes help quicker recovery.
- Personality: Outgoing cats might become clingy, while shy ones withdraw more. Some “blossom” without the other cat, becoming more active.
On average, visible signs fade in weeks, but full adjustment takes up to six months.
Stages of Feline Mourning
Cats often go through three practical stages, based on behavior experts:
- Searching Phase: Short, lasting days. Your cat paces, meows loudly, or checks hiding spots. They might wait by doors, expecting the other cat’s return.
- Depression Phase: Longer, weeks to months. They eat less, sleep more, or hide. Energy drops; play stops. This mirrors human sadness but stems from routine disruption.
- Acceptance Phase: They adjust, perhaps bonding more with you. Permanent changes, like more affection, may stick.
Examples: A cat in Texas searched for her sister for a week, then slept in her bed for months before perking up.
Common Signs of Grief in Cats
Watch for these real behaviors after the loss:
- Appetite Changes: Many skip meals or eat half. A study showed 46% of grieving cats ate less.
- Sleep Shifts: More napping or insomnia. They might choose new spots, avoiding shared ones.
- Vocalization: Increased meowing or yowling, like calling for the lost cat. One owner reported constant cries for weeks.
- Behavioral Shifts: Clingy with you, or withdrawn and hiding. Some become aggressive toward other pets.
- Searching and Pacing: Wandering rooms, sniffing toys or beds. This is common early on.
- Lethargy or Overgrooming: Less play, more grooming from stress. Watch for bald spots.
These signs overlap with illness, so rule out health issues first.
When Should You Be Concerned?
Most grief resolves naturally, but worry if signs persist or worsen. Contact your vet if:
- No Eating for Days: Cats can develop fatty liver disease (hepatic lipidosis) quickly fatal if untreated. If they skip food for 2-3 days, seek help.
- Extreme Withdrawal: Hiding constantly for over a week, ignoring you entirely.
- Aggression or Self-Harm: Lashing out or overgrooming to injury.
- Lasts Over Months: If no improvement after six months, it might signal deeper issues like anxiety.
- Other Symptoms: Vomiting, diarrhea, or weight loss could be grief-stressed illness.
In the USA, vets like those at VCA recommend check-ups for peace of mind. Early intervention prevents complications.
What Should Pet Owners Do?
You can ease your cat’s mourning with simple, caring steps. Focus on stability and support.
- Keep Routines Steady: Feed, play, and clean litter at usual times. This reduces stress from change.
- Offer Extra Attention: Pet, groom, or sit quietly together. If they seek cuddles, provide them helps fill the void.
- Encourage Play: Use toys like feather wands to distract and boost mood. Short sessions rebuild energy.
- Use Calming Aids: Feliway diffusers mimic comforting pheromones. Ask your vet about supplements if needed.
- Tempt Appetite: Offer favorites like tuna or wet food. Warm it slightly for appeal. If no luck, try baby food (meat-only) or consult vet for appetite stimulants.
- Delay New Pets: Wait months rushing adds stress. Let your cat grieve fully first.
- Monitor Health: Weigh weekly; track eating. Vet visits ensure no underlying problems.
- Show the Body if Possible: Letting them sniff the deceased helps some understand reduces searching.
Be patient; your care makes a difference.
