Cats with food poisoning will not get better immediately after receiving a detoxification injection. It will take a period of digestion and recovery. After the injection, they will have a loss of appetite, body strength, and unable to stand upright, but they will be conscious of the owner’s cries. The owner can feed the cat some clean water to help the cat digest the injection. If the cat improves significantly after one day, it can return to its original state; if the cat does not improve, it still needs to be sent to a doctor for treatment.
