What to Do If Your Cat Gets Sick in Kew: Emergency Steps
Summary: If your cat seems unwell, keep them calm, watch for key signs such as breathing difficulty, collapse, repeated vomiting, severe pain or trouble passing urine, and contact a vet promptly. For urgent situations, use our Emergency Vetcare information. If your cat needs to be seen, you can also arrange an appointment through our Online Booking page.
Introduction
When a cat becomes unwell, it can be hard to know whether to monitor them at home, book an appointment, or seek urgent help straight away. Cats are very good at hiding illness, so even small changes in appetite, toileting, grooming or behaviour can matter.
At Kitten to Cat we regularly help local cat owners in Kew, Richmond and West London work out what to do when their cat is sick. As a dedicated cat-only veterinary clinic, we understand how stress, environment and subtle signs can affect feline health. Our aim is always to help you act early, stay calm and get the right support for your cat.
If you are worried, it is always sensible to speak to a veterinary professional. Our experienced feline veterinary team supports cats across Richmond, Kew and West London with both urgent and routine care, and you can register your cat with us if you are new to the practice.
Emergency steps if your cat gets sick
If your cat suddenly seems unwell, these are the most important first steps:
- Keep your cat calm and somewhere quiet. Cats often feel more stressed when handled too much. Move them to a safe, warm room if possible.
- Observe before you act. Check whether they are alert, breathing normally, able to stand, and whether they have vomited, had diarrhoea, or tried to use the litter tray.
- Do not give human medicines. Many common medicines that are safe for people are dangerous for cats.
- Remove food for a short time if they are actively vomiting, but keep water available unless a vet advises otherwise.
- Use a secure cat carrier. A proper carrier helps keep your cat safe and reduces stress during travel.
- Contact a vet if you are concerned. For urgent help, use our Emergency Vetcare page. If your cat needs a non-emergency appointment, you can use our Online Booking system.
If your cat is struggling to breathe, has collapsed, is having a seizure, has eaten something toxic, cannot pass urine, or is in severe pain, contact a vet immediately.
Signs that may mean your cat needs urgent veterinary attention
Our feline veterinary team often advises owners to trust changes that feel out of character. In our experience supporting cats across Richmond and West London, the following signs should not be ignored:
- Breathing that is fast, laboured or open-mouthed
- Collapse, extreme weakness or inability to stand
- Repeated vomiting or vomiting with lethargy
- Straining in the litter tray, especially if little or no urine is passed
- Sudden loss of appetite, particularly if your cat normally eats well
- Severe lethargy or hiding much more than usual
- Suspected poisoning, including lilies, antifreeze, human medication or household chemicals
- Bleeding, trauma, bite wounds or obvious pain
- Seizures or unusual neurological signs such as disorientation
Cats are not small dogs, and their warning signs can be quieter. A cat sitting still, hiding, or refusing food may be much more unwell than they appear. If you are unsure whether a problem is urgent, please speak to a vet.
Common reasons cats suddenly seem unwell
Many local cat owners ask us what “sick” can look like in cats. It is not always dramatic. We commonly see:
- Vomiting or diarrhoea
- Reduced appetite
- Constipation or trouble using the litter tray
- Urinary problems
- Respiratory infections causing sneezing or nasal discharge
- Dental pain leading to quiet behaviour or poor appetite
- Stress-related changes after moving house, visitors or household disruption
- Fever, pain or inflammation linked to underlying illness
At Kitten to Cat we regularly help owners who notice very small changes first, such as less grooming, more hiding, sleeping in unusual places, or not jumping up as normal. Those details are often very useful when we examine your cat.
If your cat is due for a routine check or you want to be proactive about their health, our Health Checks and Clinics and Preventative Healthcare services can help spot concerns early.
What We Commonly See at Kitten to Cat
One of the most common concerns we hear from cat owners in Kew and across West London is, “My cat just isn’t themselves, but I can’t tell what is wrong.” That is very typical for cats.
As a dedicated cat-only veterinary clinic, we regularly help owners whose cats are:
- Eating less but still appearing bright
- Vomiting once or twice, then seeming quiet afterwards
- Making frequent trips to the litter tray
- Hiding more than usual after a stressful event
- Showing subtle signs of pain, such as crouching or reluctance to be touched
A common misunderstanding is that if a cat is purring, they cannot be in pain. In fact, some cats purr when they are anxious or uncomfortable. Another common misconception is that indoor cats do not need regular veterinary checks. In reality, indoor cats can still develop dental disease, urinary issues, weight problems and age-related illness.
Our award-recognised feline team regularly helps local cat owners distinguish between mild stomach upsets, stress-related behaviour changes and symptoms that need urgent attention. Because our clinic has been designed specifically around feline comfort and wellbeing, we can often assess unwell cats in a calmer, cat-focused environment. If your cat needs ongoing care, you can also explore our full range of services and, where appropriate, our Advanced Surgery and Medicine support.
Practical advice for cat owners in Kew
1. Make a note of what has changed
Before calling the vet, it helps to note:
- When your cat last ate and drank
- Whether they have been sick or had diarrhoea
- Whether they have urinated and passed faeces normally
- Any possible toxin exposure
- Any recent falls, injuries or fights
- Changes in behaviour, energy, grooming or breathing
2. Use the carrier well
Our feline veterinary team often advises placing familiar bedding in the carrier and covering part of it with a towel. This can make travel less stressful. Avoid chasing your cat if possible, as panic can make assessment harder.
3. Do not wait too long for appetite changes
Cats that stop eating can become poorly quite quickly, especially overweight cats. If your cat has a sudden appetite loss or is refusing food, arrange veterinary advice promptly. If you need to plan routine support for long-term health, our VIP Health Plan and Cat VIP Plan may be helpful for preventative care.
4. Check the litter tray
Changes in urination are particularly important in cats. Straining, frequent visits, crying in the tray, or little urine being produced can indicate a serious problem. This is one situation where prompt veterinary attention matters.
5. Keep up routine healthcare
Prevention matters even for indoor cats. Regular health checks, parasite control and weight monitoring can help us pick up problems early. If you have a young cat or kitten, our Kitten VIP Plan and Free Kitten Health Checks can support a healthy start. For adult cats, we are always happy to help you book an appointment for a wellbeing visit.
When To Contact A Vet
Please contact a vet promptly if your cat:
- Is not eating or drinking normally
- Has repeated vomiting or diarrhoea
- Seems quieter, weaker or more withdrawn than usual
- Has trouble passing urine or faeces
- May have eaten something harmful
- Has breathing changes, injuries, swelling or signs of pain
At Kitten to Cat we commonly see cats whose symptoms started subtly but became clearer over several hours. Early advice can make a real difference. If you need urgent support, use our Emergency Vetcare information. If the issue seems non-urgent but your cat should be assessed, you can arrange a visit through Online Booking.
If you are new to Kitten to Cat, you can also register your cat online. Our experienced team is proud to support cats across Richmond, Kew and West London, and we were shortlisted at the Best UK Vets Awards 2024.
Frequently Asked Questions
Should I feed my cat if they have vomited?
If your cat has vomited once but seems otherwise comfortable, it may be reasonable to pause food briefly and then offer a small amount later. However, repeated vomiting, lethargy, or refusal to eat should prompt veterinary advice.
How do I know if my cat’s illness is an emergency?
Breathing difficulty, collapse, seizures, severe pain, poisoning, trauma, or inability to pass urine are emergencies. If you are unsure, contact a vet for guidance rather than waiting.
My cat is hiding. Does that always mean they are ill?
Not always. Cats may hide when stressed, tired or unsettled. However, if hiding is unusual for your cat or is combined with poor appetite, quiet behaviour or litter tray changes, it is best to seek advice.
Can I wait until tomorrow?
Sometimes mild signs can be monitored for a short period, but cats can deteriorate quietly. If your cat is not eating, seems painful, has urinary changes, or you are worried, contact a vet sooner rather than later.
Do indoor cats still need regular vet visits?
Yes. Indoor cats still benefit from routine health checks and preventative healthcare. We commonly see conditions in indoor cats that owners could not have prevented without regular monitoring.
