Cats can do B-ultrasound to observe the fetal condition in about 45 days. The price of B-ultrasound will vary from region to region. The more developed places may be more expensive, probably 120-200. B-ultrasound is a necessary means to distinguish whether the fetus is healthy or not. If you want to see the number and location of the fetus, you need to use X-ray or DR, and the price is between 150-300.

Precautions:
Generally speaking, kittens should be fed a few times less, and big cats should be fed regularly and quantitatively.
Cats during pregnancy should be fed more, and the veterinarian's advice should be followed, and the nutrition should keep up. In the first four weeks of life, kittens should be completely breastfed (100% of the nutrition is obtained from breast milk).
Pay special attention to the diet of kittens in the fifth week, and generally prepare high-calorie food for them. Feed it about 5-6 times a day during weaning, usually for several weeks, so that the kitten's nutrition can keep up.
