About this guide: Written by cat parent and Pawfect Cat Care founder Hicham Aouladi and fact-checked using reputable veterinary sources. For educational purposes only — not a substitute for professional veterinary advice.
I’m Hicham, the cat parent behind Pawfect Cat Care. When a summer heatwave turned my small apartment into a little oven, I realised I didn’t actually know what counted as “too hot” for my own cat or how fast heatstroke could happen. This guide is the calm, step-by-step version of everything I wish I’d had that week.
Summer heat waves can turn a comfy apartment into a sauna — especially for indoor cats. This no-panic guide shows what heatstroke looks like in cats, what to do first, and simple home tweaks to keep your feline cool and well hydrated. Educational only — seek veterinary care for emergencies.

1. What counts as heatstroke in cats?
Veterinarians commonly define heatstroke in cats as a core temperature above 104°F (40°C). Heat exhaustion often appears just before that — catching it fast helps prevent organ damage. A normal cat rectal temperature is roughly 100.5–102.5°F (38.1–39.2°C).
2. Why “indoor only” isn’t always safe
It’s easy to think: “My cat stays inside, so we’re safe.” But closed rooms trap heat — especially sunrooms, upstairs bedrooms, and spaces with poor airflow. Glass windows act like little greenhouses, and soft furniture holds onto warmth.
During a heatwave, a room that feels fine at 10 a.m. can quietly slide into the high 80s°F (around 31°C) by afternoon. Power cuts or AC cycling make it worse. Senior cats, flat-faced breeds, overweight cats, and those with heart or breathing issues are often the first to struggle.
Watch for the “I’m getting hot” clues:
- Moving to tiles or the bathtub to lie flat.
- Panting (even a little) or hanging out near door gaps and drafts.
- Hiding in the darkest, lowest parts of the home.

3. Early & advanced signs
- Early Seeking cool floors/shade, panting (unusual for cats), drooling, sweaty paw pads, extra drinking, excessive grooming.
- Advanced Disorientation, red gums, vomiting/diarrhea, laboured breathing, collapse, seizures; rectal temp > 104°F.
4. First-aid: cool first, then the vet
- Move the cat to a shaded, comfortably cool area; start travelling to the nearest vet/ER.
- Apply room-temperature wet towels to neck, armpits, and groin; re-wet every few minutes. Use a fan if available.
- Do NOT use cold/ice baths — rapid cooling can worsen the condition.
- Offer small sips of cool water if the cat is alert; never force water.
5. Safe home & room-by-room setup
There’s no single “magic” number for every cat. Most healthy indoor cats stay comfortable in the mid-60s to upper-70s °F when airflow and hydration are good. Watch your cat’s behaviour (panting, sprawling on tile, lethargy) and cool the space before these appear. Smart thermostats can send alerts if cooling fails.
Bedroom / lounge: Turn one room into your “cool core.” Draw curtains, run a fan near (not straight on) your cat’s bed, and keep a shallow bowl of water nearby. Elevated or mesh-style beds let air move underneath.
Kitchen / bathroom: Tile floors are your friend. Leave doors open for cross-breeze. If you use a portable AC, vent it properly and avoid blasting icy air directly at your cat — steady, gentle airflow is better.
Hallways: Put a box fan where it can pull in cooler air from the shadiest side of the home. Tidy cables so curious paws don’t get tangled.
Carrier corner: Leave the carrier open with a soft towel inside. If you ever need a fast vet trip in a heat emergency, you won’t be hunting for it while you’re worried. For calming setup ideas, see Cat Anxiety: Signs & Solutions.
6. Hydration hacks cats actually use
- Place multiple wide, shallow bowls around the home and refresh often.
- Bowls on each floor or in every “nap zone” so water is always close.
- Offer cool water; a few ice cubes can entice some cats (skip if yours dislikes them).
- Boost moisture with wet food or by adding a spoon of water to meals.
- Water fountains help picky drinkers who love moving water.
- Ask your vet before using any broths; choose low-sodium, onion/garlic-free options only if approved.

7. Room-comfort helper (interactive)
Simple guide only (not a medical device). Use behaviour + thermometer to judge comfort.
Suggestion: Likely comfortable for many healthy indoor cats
8. Windows & cars: hidden summer dangers
Cars: Never leave a pet in a parked vehicle — even “just for a minute.” Cabin temperatures can rise dangerously fast.
- On warm days, car interiors can jump tens of degrees in minutes — choose vet visits early/late in the day and pre-cool the car.
- Travel tip: place the carrier on the floor behind a front seat (shade) and aim airflow toward — not directly into — the carrier.
- Keep a small bottle of water and a spare towel in the car for emergencies.
Windows / balconies: Open windows + curious cats can lead to falls (“high-rise syndrome”). Use snug screens and supervise balcony time.
- Install tight-fit screens; avoid tilt-only openings that create “trap gaps”.
- Create shade at windows (film or curtains) and move beds away from direct sun spots in the afternoon.
9. Quick & printable heatwave checklist
- Keep living spaces below your cat’s panting point; ensure shade and airflow.
- Refresh cool water often; add ice cubes only if your cat likes them.
- Set up a “cool zone”: tile floor + fan + damp towel rest spot.
- Secure window screens; no unattended balcony time.
- Never leave pets in cars. If overheating signs appear, start safe cooling and go to a vet.
| Task | Done | Notes |
|---|---|---|
| Set up a shaded “cool core” room with fan/AC and blackout curtains | ◻ | Keep doors open for airflow |
| Place 2–3 extra water stations (wide, shallow bowls) | ◻ | Refresh twice daily |
| Switch to wet food for higher moisture intake | ◻ | Split into smaller meals |
| Prep safe DIY cooling (towel-wrapped frozen bottle near bed) | ◻ | Never place directly on the cat |
| Move daytime nap spots away from sun-exposed windows | ◻ | Check rooms during peak heat |
| Keep carrier accessible and ready (soft towel inside) | ◻ | Faster exits for vet visits |
| Know red-flag symptoms & vet number | ◻ | Post near the fridge |
10. FAQ
Is shaving a cat for summer a good idea?
Generally no. Brushing to remove mats helps, but full shaves remove skin/sun protection. Discuss trims with a vet or pro groomer if there’s matting or medical need.
Do fans help cats?
Fans improve airflow and help towel-cooling work better. Combine fans with shade and hydration; fans alone don’t lower room temperature.
What’s “too hot” indoors?
Once rooms push into the upper-70s to low-80s °F and your cat starts panting, sprawling on tile, or acting lethargic, it’s time to cool the space or relocate temporarily.
