Unless she is spayed, a queen will go into heat every one to three weeks until a male cat (called a tom, not a king, just so you remember who’s in charge) impregnates her. What to do when your ...
It was once believed that female cats and dogs should not be spayed until the animal delivered one litter or, at least, experienced one estrus or “heat” cycle. (There was little concern about neutering males, other than for behavioral reasons, since males do not get pregnant.)
Female cats should be spayed before their first heat, as each cycle of heat creates a greater risk of mammary cancer. Spaying a female cat requires the removal of the ovaries and uterus, which would eliminate their chances of developing cancer in these areas. [18]
Some species, such as cats, cows and domestic pigs, are polyestrous, meaning that they can go into heat several times per year.

The risks for sick animals were 1.33% for dogs and 1.40% for cats. [43] Spaying and castrating cats and dogs may increase the risk of obesity if nutritional intake is not reduced to reflect the lower metabolic requirements of neutered animals. [44] In cats, a decrease in sex hormone levels seems to be associated with an increase in food intake ...
Pyometra is a result of hormonal and structural changes in the uterus lining. This can happen at any age, regardless of how many heat cycles have occurred or previous pregnancies (or lack thereof), although it becomes more common as the dog gets older. The main risk period for a female is for eight weeks after her peak standing heat has ended. [2]
Female dogs who are not spayed or who are spayed later than the first heat cycle are more likely to develop mammary tumors. Dogs have an overall reported incidence of mammary tumors of 3.4 percent. Dogs spayed before their first heat have 0.5 percent of this risk, and dogs spayed after just one heat cycle have 8 percent of this risk. [1]
