Cats often exhibit rapid breathing before death. If a cat's heart fails, its lungs become less efficient, leading to a decrease in blood oxygen levels. To absorb more oxygen, the cat's breathing becomes rapid. Later, fluid buildup in the lungs can cause breathing difficulties, resulting in heavy and slow breathing.
Cats often stop eating before they die. As cats approach death, they may stop eating altogether, and some may even refuse water. Furthermore, their bodies may change due to anorexia. They may appear extremely gaunt, with thinning skin, sunken eyes, and other signs of weakness.
A cat's body temperature will drop before it dies. A cat's normal body temperature is generally between 38 and 39.5 degrees Celsius. When a cat's body odor decreases, its body temperature will gradually decrease. When its heart fails, its body temperature will drop below normal. If you notice that your cat's body temperature is low at home, you should take it seriously and take it to the vet immediately.
