Female Cat - Seasons

[Bellybee]

We really want to get our female cat neutered (sp) but she is or seems to be constantly in season and the vet wont do it. She literally has a one day break every fortnight

This's the normal cycle of a female cat. Some vets will still spay a cat even though she is in heat, it's harder to do because things are swollen and engorged, but it can be done. You have 2 choices if you want her spayed: find one that will, or wait till she is between cycles.

From "Talk to the Vet .com"

Estrus ("heat") is the mating period of female animals. When estrus occurs, animals are said to be "in heat" or "in season." Cats normally have their first estrous cycle between 5 and 10 months of age, with the average age around 6 months. 

  The female cat has 2-4 estrous periods every year, each lasting 15-22 days. If she is bred, estrus seldom lasts more than 4 days.

  If successful mating does not occur, estrus may last for 7-10 days and recur at 15- to 21-day intervals. It is possible for an unmated female to cycle every 3-4 weeks indefinitely. 

  Cats also have an estrous period 1-6 weeks after giving birth, so a female may be nursing one litter while pregnant with another.
