How to care for a cat that is sick
Watching a cat be sick is uniquely stressful. They hide their pain so well that by the time you realize something's wrong, it can be serious. Cats are also notoriously difficult to examine at home (try getting a cat to let you look in their mouth). The good news: you know your cat better than anyone. The small changes you notice are usually the early signs of something real. Trust what you see, even when the cat is acting 'fine' otherwise. This isn't a substitute for veterinary care. If you suspect something is wrong, get to the vet. But here's how to tell what's worth watching versus what's worth an emergency visit, and how to care for a sick cat at home.
Know the warning signs that need immediate vet attention
Some signs mean 'get to the vet now, not tomorrow':
- Difficulty breathing (open-mouth breathing, rapid breathing, blue gums)
- Collapse or extreme lethargy
- Inability to urinate (especially male cats — this is a true emergency)
- Straining to urinate with no output
- Severe vomiting (multiple times per hour, or with blood)
- Suspected toxin ingestion
- Trauma (hit by car, fall, attack by another animal)
- Pale or white gums
- Seizures
- Bloated, hard abdomen
- Eye injuries
If you see any of these, don't wait. Don't call first — go. Many of these are life-threatening within hours.
For the 'go now' situations, call the vet on your way so they're prepared. Many emergency clinics can guide you on what to do while you're in transit.
Watch for the subtle signs
Many serious conditions in cats show up as subtle behavior changes:
- Eating less (or more)
- Drinking more water than usual
- Hiding more than usual
- Less grooming (looks unkempt)
- More grooming of one specific area
- Sleeping more or in unusual places
- Changes in litter box habits (frequency, location, posture)
- Weight loss (even small amounts)
- Bad breath that's new
- Drooling
- Vocalizing differently
Cats are masters at hiding illness. By the time they're obviously sick, they've often been subtly sick for days or weeks. If you notice anything different, mention it to your vet.
Don't wait to see if it gets better on its own. Cats don't get better from serious illness on their own. They get worse.
Get them to the vet
If you suspect something is wrong, see the vet. Don't self-diagnose from the internet. Don't wait. Don't try home remedies first.
What to expect:
- Physical exam
- Possibly bloodwork (CBC, chemistry panel)
- Possibly urinalysis
- Possibly imaging (x-rays, ultrasound)
- Possibly more specific tests
Treatment depends on diagnosis, but common options:
- Antibiotics for bacterial infections
- Anti-nausea medication
- Fluid therapy (subcutaneous or IV)
- Prescription diets for kidney, urinary, or GI issues
- Pain medication
- Surgery for some conditions
Ask questions:
- What's the diagnosis?
- What's the treatment plan?
- What should I watch for at home?
- When should I bring them back?
- Are there any side effects of the medications?
Take notes. You'll forget half of what the vet says.
Administer medication at home
Giving medication to a cat is one of the great challenges of pet ownership. Here's how to actually do it.
Pills:
- 'Burrito' the cat in a towel, leaving only the head out
- Hold from behind, tilt head back
- Open mouth by pressing on the sides of the jaw
- Drop pill as far back on the tongue as possible
- Close mouth, blow gently on the nose or stroke the throat to encourage swallowing
- Give a treat or wet food immediately after
Liquid medication:
- Use the syringe provided
- Same burrito technique
- Insert syringe in the side of the mouth, between the cheek and teeth
- Squirt slowly, allowing the cat to swallow between squirts
Topical medications:
- Apply to the back of the neck where they can't lick it
- Part the fur so it goes on the skin, not the fur
- Don't let other pets groom the area for 24 hours
If you absolutely can't do it, ask your vet about:
- Transdermal medications (applied to the ear)
- Compounding pharmacies that make medications into flavored liquids or treats
- Long-acting injectable versions of some medications
Make them comfortable during recovery
A sick cat needs a calm, quiet space to recover:
- A small, quiet room away from household chaos
- Easy access to food, water, and litter box (all on the same floor)
- A comfortable bed in a warm spot
- Limited jumping (keep them on one floor if possible)
- Soft lighting
- Your presence (or another calm pet's presence) for comfort
Encourage eating:
- Warm up wet food (increases aroma, makes it more appealing)
- Try different textures (pate vs chunks vs shreds)
- Offer treats they love (within dietary restrictions)
- Hand-feed if needed
- Some cats need appetite stimulants from the vet
Encourage drinking:
- Multiple water bowls in different locations
- A cat water fountain (many cats prefer running water)
- Add water to wet food
If they refuse food for 24+ hours (especially overweight cats), this is a vet emergency. Cats who don't eat can develop hepatic lipidosis (fatty liver disease) which is life-threatening.
Know when it's time to say goodbye
The hardest part of having a cat is also one of the last things you'll do for them. At some point, you may face the decision about euthanasia.
Quality of life considerations:
- Are they still eating and drinking?
- Can they move around without significant pain?
- Are they engaging with you at all?
- Are they having more bad days than good days?
- Can they do the things that make them 'them'?
- Is treatment more burdensome than the disease?
Your vet can help you assess this objectively. Quality-of-life scales (HHHHHMM scale) are useful tools.
When it's time:
- In-home euthanasia is available in most areas
- Your cat passes peacefully in their favorite spot
- You're there, holding them
Grief is real and valid. Don't apologize for how hard this is. Cats are family, and losing them is losing family.
If you're struggling with the loss, pet loss support groups (online and in-person) exist. Rainbow Bridge, Lap of Love, and your vet can direct you to resources.
