Losing a cat is heartbreaking. It affects us deeply as humans – but it can also affect the cats left behind. Many people wonder: do cats grieve the loss of another cat? The answer is yes. Cats form bonds with their feline and canine companions, and when that pet dies, the surviving cat may show signs of grief. They may become quieter, lose their appetite, or wander the house as though searching for their missing friend.
While cats may not express emotions in the same way we do, research and experience show that they can mourn. Recognising the signs a cat is grieving is the first step in helping them adjust to life after the loss of another cat in the home.

Do cats understand when another cat has died?
Cats may not understand death the way humans do, but they are highly sensitive to absence, scent, and routine.
When another cat suddenly disappears, the surviving cat notices. They may sniff around favourite resting places or call out as if searching. Some experts believe allowing a cat to see and smell their companion’s body after death can help them register the change and reduce searching behaviour.
So while cats may not grasp the concept of death itself, they certainly recognise when a companion is gone, and this awareness can trigger grief.
Do cats grieve the loss of another cat
Cats build strong connections, not only with us but with other pets in their household, especially if they shared a daily routine together. Cats are creatures of habit, so the sudden absence of a familiar presence – whether it’s a playmate, sleeping buddy, or even a rival – can be unsettling.
Typical grieving cat behaviour includes:
- Loss of appetite – A grieving cat may eat less or stop eating for a while.
- Increased vocalisation – Some cats cry out as if calling for their missing friend.
- Searching behaviour – Cats often roam, sniffing favourite spots and checking hiding places, seemingly looking for the other cat.
- Sleep changes – Some sleep more than usual, while others are restless and unsettled.
- Withdrawal – A grieving cat may hide, avoid play, or turn away from affection.
The ASPCA Companion Animal Mourning Project found that over 65% of cats showed noticeable changes in behaviour, including reduced appetite, increased vocalisation, and disrupted sleep patterns after losing a companion. For many owners, it’s a clear sign that pets do indeed mourn each other.
How long do cats grieve the loss of another pet?
Every cat grieves in their own way, and there’s no set timeline for how long the sadness lasts. Some cats may begin to adjust within a couple of weeks, while others show signs of mourning for several months.
It often depends on how close the bond was between them. A strongly bonded pair may leave one cat feeling lost for a long time, while a more casual relationship might result in only subtle changes.
If your cats groomed each other, played together, or slept side by side, the surviving cat is more likely to show strong signs of grief. They may linger in their companion’s favourite spots, hide or become unusually clingy with you.
Even cats who weren’t best friends still notice change. Losing another cat means losing part of their daily routine. Some cats may vocalise more, act restless, or even seem unsettled. Interestingly, a cat that lived with a rival sometimes appears calmer or happier after that cat’s passing – proof that cat grief is complex and individual.
Look for small signs of improvement over time – interest in food, willingness to play, or returning to normal sleep patterns. If your cat seems stuck in grief or becomes more distressed rather than better, it may be time to seek help from a veterinarian or behaviourist.
Should I get another cat to help my grieving cat?
Many owners wonder if bringing home a new cat will ease the sadness. The truth is, it depends on your cat’s personality and how they’re coping.
Some cats benefit from a new companion in time, but introducing another cat too soon can cause stress rather than comfort. It’s usually best to wait until your grieving cat has had time to adjust and is showing signs of stability before considering a new friend.
If you do decide to adopt again, go slowly with introductions and be prepared for an adjustment period. Another option is fostering a cat temporarily, which lets you see how your cat responds to new company without making a permanent commitment.
How to help a grieving cat after the loss of another pet
Supporting a cat mourning another cat takes patience, consistency, and love. While you can’t explain what happened, you can make the adjustment easier.
- Keep their routine steady. Stick to familiar feeding times and daily play. Routine helps your cat feel safe when their world feels uncertain.
- Offer affection at their pace. Some cats crave extra closeness when grieving; others want more space. Let them guide you, whether that means brushing, petting, or quiet companionship.
- Create a calming environment. Pheromone diffusers like Feliway, soft music, and cosy resting spots can help your cat feel secure as they process their loss.
If your cat’s appetite loss or behaviour changes persist beyond a few days, it’s wise to check with your vet. Grief can be the cause, but sometimes an illness hides beneath the stress.
What’s the difference between cat grief and illness?
Because grief can cause changes in appetite, energy, and litter box habits, it’s sometimes hard to know whether your cat is mourning or sick. While it’s normal for a grieving cat to act differently for a short time, ongoing or severe symptoms should never be ignored.
If your cat refuses food for more than 48 hours, is losing weight, or develops unusual litter box behaviours, it’s important to see a vet. Stress from grief can sometimes make existing health issues worse, or an unrelated illness could be mistaken for mourning. When in doubt, professional advice is always the safest choice.
Supporting yourself while helping a grieving cat
It’s natural to focus on your cat’s emotions, but don’t forget your own. Losing a pet is incredibly hard, and supporting a grieving cat while you’re grieving yourself can feel overwhelming.
Take comfort in small rituals – lighting a candle, creating a photo memory book, or simply talking to friends who understand the bond between pets. Sharing your grief with your cat, spending quiet time together, and offering gentle affection can be healing for both of you.
Final thoughts
So, do cats grieve the loss of another cat? Absolutely. Cats can feel the absence of a bonded companion deeply, and even less-close housemates may react to such a change.
By offering patience, extra affection, and keeping routines steady, you can help your surviving cat navigate their grief. Over time, they will find a new rhythm, and so will you. Grief, for both humans and cats, is a journey – but with love and understanding, healing does come.
