TL;DR: If your unspayed cat is yowling and rolling on the floor, she is likely in heat, which is a normal behavior and not a medical emergency. You should consult a veterinarian if your cat is already spayed, stops eating, or stops using the litter box.
Why is my unspayed female cat rolling and yowling?
- Rolling on the floor and rubbing against furniture.
- Loud, persistent meowing or vocalizing with yowls.
- Increased affection and attention-seeking.
- Assuming a posture with the front end down and the rear end raised.
Is it a medical emergency if my cat is in heat?
- The urgency level for this situation is Low; this is a normal hormonal process.
- Behaviors may last for several days and can be very noisy.
- Contact your veterinarian if your cat is already spayed and exhibiting these signs.
- Schedule a check-up if your cat stops eating or stops using the litter box.
How can a photo or video help a professional triage my cat?
- A short video captures specific body language, such as "treading" with the back legs.
- Seeing the behavior helps professionals distinguish between hormonal cycles and physical pain.
- Video evidence helps rule out other medical issues, such as urinary tract infections.
Clinical Context (Merck Veterinary Manual)
Queens reach sexual maturity by approximately six months of age, are induced ovulators, and generally cycle seasonally, most often from winter to summer, about every three weeks if not bred. Rolling and vocalization in a female cat may indicate estrus, a period of sexual receptivity.
