Persians are calm, low-activity cats with dense long coats and flat faces. Each of those traits makes weight easy to gain and hard to see.
Ideal weight
| Type | Ideal range |
|---|---|
| Persian | 3.2–5.5 kg (7–12 lb) |
Flat face, hidden body. Persians are brachycephalic (flat-faced), so extra weight can worsen breathing, and their thick coat completely hides body shape. Combined with a sedentary nature, that makes obesity easy to miss. Feel through the coat for ribs and waist, and keep this low-energy cat's portions modest.
How to tell if your pet is overweight
- Feel for the ribs. Lay both hands flat on the ribcage; you should feel ribs easily under a thin layer without pressing.
- Look from above. There should be a clear waist tucking in behind the ribs; a straight or bulging outline means no waist.
- Check the side profile. The belly should tuck up behind the ribcage rather than hang level.
What to do about it
- Weigh the food, don't scoop it. Eyeballing portions is the most common cause of overfeeding.
- Count treats as calories — keep them under 10% of daily intake; swap biscuits for carrot or green bean.
- Build up daily activity gradually, switching to low-impact options like swimming if joints are sore.
- Go slow with cats. Rapid loss risks fatty liver disease — involve your vet.
- Reweigh monthly. Safe loss is about 1–2% of body weight per week; involve your vet for an overweight pet.
