Drooling and Bad Breath Causes
There are numerous causes of poor breath and drooling in cats, and while the majority of them involve disease in the mouth, there are others.
- Oral Tumor: Inside a cat’s mouth, growths or tumors can grow, get infected, and create a foul odor. If the tumor is large enough to interfere with swallowing, your cat will have poor breath and drool. Tumors in the oral cavity can be difficult to detect because they might grow in the back of the mouth or under the tongue. Tumors are typically not detected until they create problems.
- Periodontal disease: If your cat’s teeth are not brushed on a regular basis, bacteria and food debris can accumulate. These substances can build up and cause infection, resulting in periodontal disease. Periodontal disease can also cause gum abscesses, foul smell, and drooling. If this is not addressed, your cat’s teeth may fall off or require extraction.
- Kidney disease or failure can occasionally produce foul breath in cats. Toxins are removed from the blood by the kidneys, and if they are not working properly, a toxin buildup can cause halitosis.
- Liver disease: If your cat’s breath smells like bile or vomit, liver disease may be at blame. The liver aids in detoxification and produces bile, which aids in fat digestion. However, if the liver is not functioning properly, you may notice a foul stench emanating from your cat’s mouth. Vomiting is also common in cats with liver disease, which can also cause poor breath.
