Cats inhale oxygen differently from humans. A cat's respiratory system is through the mouth and nose at the same time, so when you give your cat oxygen, you need to use an oxygen inhalation device with a mask or nose plug.
The oxygen equipment delivers pure oxygen to the cat's respiratory system to provide additional oxygen. This method of oxygenation is usually used in emergency situations such as after a cat's surgery or when the body is experiencing breathing difficulties.
It is important to note that cats need to be constantly monitored for respiratory status and blood oxygen saturation when receiving oxygen to prevent over-breathing or oxygen toxicity. If you need to provide oxygen care for your cat, it is recommended that you consult a veterinarian or a professional pet medical organization for assistance.
