Losing a pet is heartbreaking, not just for us humans, but for our feline companions too. Cats grieve the loss of another pet especially when they’ve shared a close bond. They may show signs of sadness, become less active, eat less, or even search for their missing friend.
It’s easy to assume that because cats are independent, they might not mourn like we do. But studies and observations suggest otherwise. Cats form strong emotional connections, and when a companion passes away, it can disrupt their routine and sense of security. Recognising these behaviours is the first step in helping your grieving cat adjust.

Understanding grief in cats
Much like humans, cats form strong emotional connections, and when those bonds are broken, they can experience grief. Losing a companion – whether a sibling, a playmate, or simply a familiar presence in their home – can deeply affect their behaviour and wellbeing.
While every cat reacts differently, some common signs that your cat is grieving include:
- Loss of appetite: A grieving cat may eat less or stop eating altogether due to stress or confusion.
- Increased vocalisation: Some cats become more vocal, letting out mournful cries as if searching for their lost companion.
- Searching behaviours: You may notice your cat roaming the house, sniffing familiar spots or checking places their companion used to frequent, seemingly trying to “find” them.
- Disrupted sleep patterns: Some grieving cats sleep more than usual, while others become restless and struggle to settle.
- Withdrawal: A grieving cat may retreat, spend more time hiding, or lose interest in social interaction, including cuddles and playtime.
Scientific evidence of grief in cats
You might wondering whether cats grieve the loss of another pet, or if we are simply projecting human emotions onto them?
Several studies have documented behavioural changes in cats after losing a companion. 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 – similar to grieving humans.
Feline behaviour experts also agree that cats do grieve. Cats form strong bonds, not only to their human caregivers but also with other cats in their household. When that bond is suddenly broken, the surviving cat may feel disoriented or anxious. Their heightened sense of smell and reliance on routine plays a role. When a companion’s scent lingers but their presence is missing, it can cause confusion and emotional distress.
While cats may not process grief in the same way humans do, their behaviour suggests they are affected by the loss of a familiar and comforting presence. Recognising these signs allows us to better support them through the grieving process.
The role of relationships between pets
Cats are social in their own unique way, forming attachments not only to humans but also to other pets. When a companion animal passes away, the nature of their relationship plays a major role in how the surviving cat reacts.
When cats were closely bonded
If your cats were close –grooming each other, playing together, or spending their days side by side – the surviving cat is more likely to show signs of grief. Cats grieve the loss of another pet, and losing a best friend can create an emotional void, leaving them confused or seemingly searching for their lost companion. When one cat is no longer there, the surviving cat might seem lost, lingering near their companion’s favourite spots or acting noticeably withdrawn.
Think of it this way: if you lose someone who provided comfort and security, you naturally feel their absence deeply. Cats experience something similar. Their routines and interactions, built over time, are suddenly gone, and this can manifest in significant behavioural shifts.
So, what can you do? Offer your cat extra affection, keep their daily routine as stable as possible, and maintain familiar environments. These small gestures provide security and help ease their transition during a difficult time.
When cats had a conflicted relationship
Not all feline relationships are harmonious. Some cats tolerate each other, while others bicker over territory or resources. Does this mean a cat won’t grieve the loss of a rival or indifferent housemate? Not necessarily.
Even if two cats weren’t close, the surviving pet may still react to the change. Cats grieve the loss of another pet in different ways. They thrive on routine, and the absence of a familiar presence – whether friendly or combative – can create stress.
Imagine working alongside someone you occasionally clash with. If they suddenly leave, you might still notice their absence and feel unsettled. Similarly, a cat may vocalise more, act restless, or withdraw after the loss of a housemate they didn’t particularly like.
Interestingly, some cats thrive after a pet with whom they had a tense relationship passes away. They may appear more relaxed, become more affectionate toward humans, or show positive behavioural changes – highlighting just how complex feline grief can be.
So how can you tell if your cat is struggling or simply adjusting? Keep an eye on their behaviour. Are they eating less? Do they seem withdrawn? Have they become more vocal? These subtle cues can indicate whether they’re feeling the loss.

How to support a grieving cat
If your cat is showing signs of sadness – like withdrawing, searching for their lost companion, or losing interest in food – thoughtful support can make a world of difference.
Maintain a stable routine
Cats thrive on consistency, and grief can make sudden changes feel overwhelming. Keeping their daily routine as familiar as possible provides comfort and security.
- Stick to regular feeding times to create a sense of normalcy. Routine helps cats feel safe during uncertain times.
- Keep playtime consistent. Interactive sessions with a feather toy or laser pointer can serve as both a distraction and a mood booster.
- Avoid major household changes. Rearranging furniture or introducing new elements can heighten stress.
A familiar routine can help ease their anxiety and reassure them when their world feels unsettled.
Provide extra attention
While cats may mask their emotions, grief can make them more in need of reassurance and affection.
- Engage at their pace. Offer gentle petting or brushing if they seek comfort, but give them space if they prefer solitude.
- Spend quiet time with them. Just being in the same room can be soothing without overwhelming them.
- Try calming interactions, like softly talking to them or sitting nearby during naps.
Every cat handles loss differently – some become clingier, while others withdraw. Both reactions are normal, so patience is key.
Create a calming environment
Small adjustments can help cats feel more secure and relaxed as they grieve the loss of another pet.
- Use calming pheromone diffusers like Feliway, to help reduce stress.
- Play soft, feline-friendly music to create a soothing atmosphere.
- Provide cosy spots with familiar bedding and toys, giving them a safe space to retreat when needed.

If their grief persists or significantly affects their eating, drinking, or overall behaviour, consider a vet visit. Professional guidance can help address emotional distress or underlying health concerns.
Supporting a grieving cat requires patience, stability, and love. While every cat is unique, these gentle strategies can help them adjust and find comfort after loss.

When to seek veterinary help
Helping your cat through grief can be challenging, especially when their behaviour raises concerns. While many cats gradually adjust, some struggle with prolonged or severe symptoms that may require professional support. Recognising when to seek help from a veterinarian or animal behaviourist is essential for safeguarding your cat’s emotional and physical wellbeing.
Signs your cat may need extra support
It’s natural for cats to grieve the loss of another pet, but some signs suggest they may need additional help. If you notice any of these behaviours lasting more than two weeks, it’s time to consider professional advice:
- Loss of appetite: If your cat is eating significantly less or refusing food altogether for more than 48 hours, they risk developing hepatic lipidosis, a dangerous liver condition.
- Avoidance of activities: Grieving cats may lose interest in play, grooming, or other routines they once enjoyed.
- Litter box issues: Ignoring the litter box or developing unusual elimination habits may indicate emotional distress.
- Agitation or increased vocalisation: If your normally quiet cat becomes excessively vocal, anxious or even aggressive, grief may be overwhelming them.
These symptoms may stem from grief alone or be exacerbated by an underlying medical condition. Trust your instincts – if something feels off, seeking help early can make all the difference.
Options for support
If your cat is struggling with prolonged grief, you’re not alone—there are professionals who can help.
- Veterinarians: Your first point of contact should be a vet. They can assess your cat’s physical health and rule out medical conditions that mimic or worsen grief. For example, a loss of appetite may stem from emotional distress or an unrelated illness
- Animal behaviourists: Specialists in feline behaviour can offer tailored strategies if your cat is withdrawing, hiding excessively, or becoming aggressive.
- Grief counsellors or pet loss specialists: Some pet owners find comfort in consulting experts who specialise in pet bereavement, offering guidance for both yourself and your grieving cat.
Grief manifests in different ways, but early intervention can prevent minor behavioural changes from turning into larger issues. Seeking professional help not only supports your cat, it also gives you peace of mind during a difficult time.
Final thoughts
Cats grieve the loss of another pet in ways that can noticeably affect their behaviour and emotions. Whether they become withdrawn, restless, or show changes in their habits, each cat processes grief differently.
Recognising these signs and offering stability, extra affection, and patience can make a world of difference in helping them adjust.
Remember that grief – both yours and your cat’s – is a journey. Take it step by step, and don’t hesitate to seek help if you notice concerning changes in your cat’s wellbeing. With time, care, and understanding, you’ll both find a new rhythm together.
