Primary signs of cat in heat are mild
But the signs get worse as the heat progresses
As the heat progresses (within 1 to 2 days since the beginning) signs usually become worse, as well as some additional signs appear:

- vocalization increases;
- cat becomes responsive to males. If you have male cats, they will also show interest in her. They will try to bite in her neck and jump on her. And, yes, even neutered male cats do this;
- attention seeking from owners and other pets, she may rug against you or wave through your legs EVEN if you do not carry a food bowl;
- hip swinging as the cat walks;
- crawling and rolling on the floor, and literally appearing to act crazy similarly like cats do when presented catnip or Valerian;
- treading of hind legs as you scratch her lower back. She may also murmur and flag her tail to the side and crouch. This method is a common test to determine whether your cat is responsive.
Usually symptoms of cat in heat lower after 4 to 10 days or in some cases, if a cat is not mated, a bit later. At the end of the heat, female cat refuses to mate and may even get aggressive if a male is approaching or trying to mate her.
