If a cat feverish from a serious disease gets an antipyretic and soon shows weakness and fast breathing, it may have a severe illness or complication; injecting fever medicine without a cause can worsen it.
Common causes: infections like panleukopenia, FIP from coronavirus mutation, or pneumonia; internal disease like heart, liver, kidney, or pyometra; toxicity; or immune, wound, or sepsis issues. With high fever and fast breathing, take it to a vet for blood, infection screening, X-ray, and ultrasound; do not self-medicate.
