Expectant female cats should pay attention not to overfeed during pregnancy, or obesity and muscle relaxation caused by insufficient exercise will cause production difficulties. The best and simplest delivery room is a cardboard box with an opening at the bottom 10- 15 cm, which is convenient for the mother cat to go in and out and prevent the kitten from falling out. And it's better to have a lid that can be opened to take care of the kitten when necessary. It's best to let the mother cat adapt to this box before giving birth 1 week, and try to spread a clean and soft towel to encourage her to sleep in it.
