A vet has warned that a change in your pet's breath could be a sign of serious illness or even indicate they are nearing the end of their life. Dr Faith Banks, a specialist in geriatric and palliative veterinary care, highlighted the symptom in a TikTok video.
Dr Banks described how she visited a couple's home to perform an at-home euthanasia for their cat when the owner mentioned their cat's breath had changed. She explained that the cat had kidney disease, which can cause a build-up of toxins in the blood, leading to an ammonia-like odour known as a uremic smell.
The vet noted that this smell can also occur in dogs with kidney disease. Other causes of bad breath in pets include infections in the mouth, tumours, liver disease, or diabetes. Diabetes can produce a sweeter smell, she added.
Dr Banks advised pet owners to contact their vet if they notice any change in their pet's breath, as it often indicates the body is not functioning properly. Early veterinary attention is crucial for diagnosis and treatment.
