Why does your cat have bad breath?

There is a multitude of possible causes for bad breath in cats, with many reasons being the same as in humans. Primary causes of bad breath are infections of teeth or the gums, a foreign body stuck in the mouth, and ulceration of the mouth. However, there are also more severe causes such as lung diseases and kidney disease. It is therefore very important that you visit your vet with your cat, not least to rule out the more serious conditions. When you visit your vet, he will also want to know if any other symptoms have been reported, such as oral discharge, change in feeding or behaviour or perhaps any other sensory changes. If it turns out that there is no detectable cause of your cat's breath, you can consider changing his diet or using a feline finger toothbrush to freshen his mouth every day or every other day.
