Kittens will be listless before they die.
If a kitten is near death, it will become listless. Normally, a cat will be quite excited, but if a kitten is about to die, it will become lethargic or even listless.
A kitten's heartbeat will slow down before it dies.
A kitten's slowed heartbeat is a sign of weakness and impending death before it dies. A cat's normal heart rate should be between 140 and 220 beats per minute. A kitten that is critically ill or extremely weak will have its heart rate drop sharply, which means that its life is about to end.
Kittens will breathe less heavily before they die.
A cat's normal breathing rate should be 20 to 30 breaths per minute. If a cat has heart failure, its lungs will work less efficiently, and the oxygen content in its blood will also decrease. In order to absorb more oxygen, the kitten's breathing will become rapid, and later, due to fluid buildup in the lungs, it will have difficulty breathing, and its breathing will become heavy and slow.
Kittens will lose their appetite before they die.
Before a kitten dies, it may experience a decrease in appetite, or even refuse to eat altogether. This is because when a kitten is dying, its entire bodily system is about to stop functioning, which leads to a decrease in appetite or even a complete refusal to eat.
