Happy Drooling: When Wet Chins Are Totally Normal
Super Happy Cats

When your cat is mega relaxed and purring away on your lap, you might spot a cheeky bit of drool.
This happy drooling happens because your cat's so blissed out they forget to swallow their spit!
It's just like when you're sleeping so deeply that drool ends up on your pillow.
A happy cat might let a bit of spit drip out when they're feeling safe and loved.
Yummy Food Time

Has your cat ever drooled while you're opening their grub?
The smell of tasty treats can make your cat's mouth water!
Their salivary glands (bits in the mouth that make spit) go into overdrive when they smell something scrummy.
Dodge the mess and feed them using their portable bowls!
Cuddle Puddles
Some cats let out a bit of drool during a good petting session.
This normal behaviour shows they trust you.

Why Does My Cat Drool? When Dribbles Spell Trouble
Tooth and Gum Troubles
One of the most common causes of cat drooling is dental issues (problems with teeth and gums).
Just like kids get cavities, cats can get tooth decay and gum disease.
When your cat's mouth is hurting, they might not want to swallow.
This causes excessive drooling.

Signs that dental problems might be making your cat drool:
- Manky breath
- Red or bleeding gums
- Not wanting to eat or poor appetite
- Pawing at their mouth like something hurts
- Weight loss

Stuff Stuck in Their Mouth

Cats are curious and sometimes get things stuck in their mouth.
A blade of grass, a tiny toy, string, or even a bug could be a foreign object stuck in your cat's mouth or back of the throat.
This can cause severe drooling.
If your cat suddenly starts drooling a lot, check to see if something's stuck.
Yucky Stuff They've Licked
Loads of household products and plants are poisonous to cats (they can make cats really poorly).
When cats taste toxic substances, they drool a lot as their body tries to get rid of the bitter taste.

Things that can make cats drool if they lick them:
- Cleaning sprays and wipes
- Electrical cords they might chew
- Poisonous plants like lilies and tulips
- Human medicines
Mouth Boo-boos
Mouth injuries like cuts, burns, or mouth ulcers can make swallowing painful.
Your cat might get oral injuries from biting something sharp, fighting with another animal, or eating something too hot.
If you notice abnormal drooling and your cat doesn't want to eat, they might have a sore in their mouth.
Big Health Problems That Make Cats Drool
Cat Colds

Cats can catch colds too!
Upper respiratory infections (like a stuffy nose and sore throat) can make cats drool because they can't breathe well through their nose.
When a cat breathes through their mouth, they might drool.
Other signs include sneezing, gunky eyes, and feeling a bit warm.
Kidney and Liver Problems
Especially in older cats, kidney disease and liver disease can cause drooling.
These health issues often make cats feel queasy, which makes them drool.
If your adult cat is drooling and also drinking loads of water, losing weight, or throwing up, it's time for a vet check.
Mouth Bumps That Shouldn't Be There

Sometimes cats can get oral cancer (bumps in their mouth) that makes them drool.
This serious health problem usually shows up as a lump in the cat's mouth.
Sometimes, they’d have rank breath, trouble eating, and excessive meowing.
The vet can spot these early if they look in your cat's mouth regularly.

Drooling When Cats Feel Nervous
Scaredy-Cat Drool
Some cats drool when they’re feeling scared.
Car rides, vet visits, or meeting new pets can cause loads of drool because they're nervous or feel a bit queasy during trips.
You can help them feel better by giving them their own cosy space.
New Foods or Medicines
A new food or oral medication might make your cat drool if it tastes rank to them.
This bad taste response usually doesn't last long, but cats can be proper drama queens with head shaking and lots of drool!
If your cat's being a total diva about taking their medicine, try wrapping them up in a towel like a cosy 'kitty burrito'.
This way, they stay snug and safe while you give them their liquid medicine—without getting scratched!
If you learn how to give an aggressive cat liquid medicine, you and your cat will be stress-free.
