Cat Health & Symptoms: A UK Owner's Guide

Hi, I'm Matt, founder of Giddy Pets. Cats are quiet, private creatures, and that's exactly what makes worrying about their health so hard — they're brilliant at hiding when something's wrong. A cat that's gone off its food, started hiding, or is grooming a little less can be telling you something important long before it's obvious. The good news is that most everyday cat health worries are common, well understood, and very treatable when you catch them early.

This hub is here to help you read the signs, do the sensible things at home, and recognise the moment a vet visit really matters. This is general guidance, not a substitute for veterinary advice — if you're worried, contact your vet.

How cats hide illness

Cats evolved as both hunters and prey, so showing weakness isn't in their nature. Instead of complaining, they tend to withdraw — sleeping more, hiding away, eating a bit less, or skipping a grooming session. Because the early signs are so subtle, the single most useful thing you can do is know your own cat's normal: their usual appetite, energy, litter-tray habits, weight and routine. When you notice a change from that baseline, you're already ahead.

A few minutes of quiet observation each day is worth more than any gadget. Watch how they eat, drink, move, toilet and rest. Run your hands over them during a fuss so you'd feel a new lump or sore spot early.

The most common cat health worries

Across this hub you'll find friendly, practical guides to the things UK cat owners ask about most:

• Tummy and appetite — why is my cat being sick, cat not eating, hairballs and constipation.
• Breathing and the nose — cat flu and cat sneezing.
• Parasites — worming your cat and getting rid of fleas.
• Wee, water and weight — UTI symptoms, kidney disease, losing weight and drooling.

To stay on top of routine prevention, our pet medicine calendar helps you track worming and flea treatments, and the parasite risk assessment gives you a quick steer on how often your cat needs protecting.

Universal red flags — when to ring your vet now

Some signs always deserve a phone call, often urgently. Contact your vet straight away — or an emergency vet out of hours — if your cat shows any of these:

• Difficulty breathing, open-mouth panting, or fast, laboured breaths
• Straining in the litter tray with little or no urine — a blocked bladder is a life-threatening emergency, especially in male cats
• Repeated vomiting, or being unable to keep water down
• Collapse, sudden weakness, or unable to use the back legs
• Pale, blue or yellow gums
• Not eating at all for 24 hours, or much longer in a kitten
• A swollen, painful tummy, or obvious severe pain
• A wound, abscess or suspected poisoning (including lilies, which are highly toxic to cats)

When in doubt, phone. A good vet would always rather reassure you over the phone than have you wait at home with a poorly cat. If you're worried about the cost of an unexpected visit, our pet emergency cost calculator and pet insurance guide can help you plan, and you can find a vet near you in our directory.

Prevention is the kindest medicine

Most of the conditions in this hub are easier to prevent or catch early than to treat once advanced. Keep up routine worming and flea control, feed a complete diet suited to your cat's life stage, keep fresh water available (our cat hydration guide explains why this matters so much), and make sure indoor cats have plenty to do — see indoor cat enrichment. Annual vet check-ups and vaccinations catch problems while they're small.

Not sure whether a food or plant is safe? Our can my pet eat this checker is a handy first stop, and you'll find sensible litter trays, water fountains and grooming kit over in the shop.

A quick word on these guides as a whole: they're written to help you feel calmer and better informed, not to replace your vet's judgement. Throughout, you'll see the same gentle theme — know your cat's normal, act early on clear changes, and never feel daft for ringing the vet. That instinct to check is one of the kindest things you can do for a creature who can't tell you what's wrong.

Browse the guides below whenever something's worrying you — and remember, trusting your instinct and ringing the vet is never the wrong call.
