Causes of dystocia in cats:

1. Excessive obesity. Overnutrition and lack of exercise lead to body obesity and fat accumulation that compresses the birth canal.

2. Physical weakness. Because cats did not supplement their nutrition in time during pregnancy, they were weak and unable to exert energy during birth.

3. The fetus is too large. If the fetus in the abdomen is too large, has a large number of fetuses, and has low fetus vitality, it will consume a large amount of calcium from the mother, leading to osteoporosis in the mother. During childbirth, it is easy to have weak uterine contractions.

4. Disease. Digestive system and parasitic diseases can consume a lot of energy in cats, causing them to be weak and difficult to give birth.

5. Pelvic hypoplasia. Due to the incomplete development of the cat's pelvis, the pelvis is narrow and deformed, making it difficult for the fetus to enter the birth canal, resulting in dystocia.
