Does your cat have bad breath? This is often a sign of serious health problems.
Here's some reasons why their breath is a bit stinky.
Bad breath in cats is something that a lot of cat owners don't realise is a big deal.
I'm Lauren Yvette and I'm here to tell you if your cat's breath stinks,
it could be a sign that something's wrong.
Let's find out why that whiff may need some attention.
When your cat has just eaten, their breath probably will smell for a little bit.
But if it smells bad all the time, that is a bad sign.
Most of the time, bad breath means poor oral health.
Clack builds up, it hardens into tartar and some nasty problems follow.
And here's the thing, cats are experts at hiding discomfort.
Your cat might seem perfectly okay,
but their breath could be giving you a clue that something is up.
So what sort of issues are we talking about?
Most often, these are dental health issues.
Bad breath can be a side effect of abscesses,
stomatitis and even of oral infections or tumours.
Systemic issues can also cause bad breath.
For example, if your cat's breath smells like ammonia or urine,
it could be a sign of kidney trouble.
And sweet smelling breath could mean diabetes.
Most cases of bad breath can be treated by improving your cat's dental care.
Ideally, brush your cat's teeth every day.
It might sound ambitious, but with patience and the right toothbrush and toothpaste,
never human toothpaste, it's totally doable.
You can also use dental chews, special diets or water additives
to help your cat's oral hygiene.
Just make sure that whatever you are doing is vet approved,
so you know it's definitely helping.
Your vet will be able to help with any existing plaque and tartar build up as well.
Having your cat's teeth professionally cleaned twice a year
is the gold standard for stopping dental issues from developing.
But remember, if your cat's breath is really bad, it's not funny or harmless.
If you are in doubt, get your cat to the vet.
If there is an underlying issue, it's best we catch it quickly.
