To tell if a cat has a fever, separate a warm-feeling nose from a temperature reading and its veterinary interpretation.
Touch, readings and reference ranges
AEC gives a pet reference of 100.5–102.4°F (38.0–39.1°C); PDSA gives 38–39°C for cats. Keep the references separate: neither is an individual diagnosis. AEC also explains that a cool nose can coexist with fever.
Changes and heat exposure
PDSA lists reduced eating or drinking, low energy, hiding and shivering among possible accompanying changes. Contact your vet if your cat seems unwell. Infection, inflammation and other circumstances can raise temperature; the changes alone cannot identify a cause or select treatment.
Heat exposure is a separate concern. Animal Trust treats suspected heatstroke as an emergency: contact veterinary care immediately if your cat may have overheated in a hot space, even if signs improve.
Make the next step specific
Describe the changes and any heat exposure. Start with what you actually noticed and when. If a reading already exists, report its value, unit, method and time. Say who obtained it and which details are unknown. Do not delay contacting the team to obtain a number. Ask when and where your cat should be seen. Write down the team's individual instructions, repeat them back and share them with anyone taking over care.
Keep household contacts in your cat care plan; use the team's directions for this concern.
