A pregnant cat is called a queen. A queens gestation period (the phase when the young are developing in the mother?s uterus (pregnancy) normally lasts for 63-65 days with the size of a litter being hree to five kittens. The first litter is usually smaller than subsequent litters.
Diagnosis of pregnancy: The earliest possible time of diagnosis could be three or four weeks after breeding. This cannot be diagnosed by a blood or urine test. However, the veterinary doctor may be able to detect
cat pregnancy by feeling the abdomen. This could be only 85% accurate diagnosis.
At six weeks of gestation, x-rays are 95% accurate when used to count the number of offspring. An ultrasound may detect foetuses as early as the second week of pregnancy, and heartbeats may be detected sometime after the third week. A queen?s both physical and personality changes tends to become more evident around three weeks after breeding.
Nutrition: High-quality nutrition is essential to the health of the queen and the kittens. A queen requires three times more than the normal intake. Give her plenty of fresh, clean water. Feed small, frequent meals. Harmful feeding practices include feeding raw egg whites, raw fish and exclusive meat or fish diets. Veterinary doctors often prescribe a special diet or supplements.
