Not necessarily, hypothermia can be caused by many reasons, including exposure to cold environments, infection, chronic disease, drug reactions, etc. However, it's important to know that hypothermia doesn't always mean a cat is beyond saving. When a cat's body temperature falls below the normal range for an extended period of time, their body organs and systems may be affected, leading to organ failure and life-threatening conditions.

Therefore, it is crucial to take timely measures to increase the cat's body temperature. Take prompt measures to raise the cat's body temperature and seek veterinary help. At the same time, we should also respect the lives of cats and make the best decisions to ensure that they receive the best care and attention.
