Being a cat owner can be difficult when it comes to health issues – cats are notoriously secretive and can try to hide when they are in pain. This means you need to be on the lookout for symptoms that something is wrong. And dental issues can be a common problem. In this article, we’ll look at a condition called stomatitis and how to spot the signs of a dental health issue. What is stomatitis in cats? Stomatitis in cats is a medical condition which causes severe inflammation to the mouth and gums of felines. This inflammation will look reddish in colour and cause cats a significant amount of pain. In some extreme cases, it can even cause bleeding in the mouth. What causes stomatitis in cats? Multiple factors are suspected to cause stomatitis in cats and the causes have still not been definitively identified. Many believe the main cause of feline stomatitis is viral infections as many cats with stomatitis have a concurrent viral infection, particularly with a virus called 'calicivirus'. Plaque and calculus are also thought to be important contributory factors.
