Yes, they do because they belong to infraclass Placentalia.
Placenta previa, placenta accreta, placenta increta, and placenta increta are all conditions stemming from abnormal implantation of the placenta.
Bats DO have bellybuttons in the sense that there is an area where the placenta was attached in the womb. In humans, it's super obvious and leaves a big scar. In other animals, you often can't see it unless you look very closely. Bats are generally furry, and small, and if you got the chance to examine one closely, you probably could see the "belly button" where the placenta was once attached.

Placenta comes out after each kitten.
The umbilical cord is attached to the placenta and the placenta is attached to the wall of the uterus
Yes. But the movement is relative. Placenta does not change the position. But lower placenta may move up. So that placenta previa may become normal placenta.
Yes kangaroos have a placenta.
Placenta Previa
No, a placenta attached to the front and back of the uterus is not considered placenta previa. Placenta previa specifically refers to a condition where the placenta partially or completely covers the cervix. In contrast, a placenta that is attached to the front (anterior) and back (posterior) of the uterus may be referred to as a bilobed or multilobed placenta, but it does not indicate previa unless it is obstructing the cervical opening.
"Unremarkable placenta" means there was nothing special, different, or noteworthy about the placenta being examined.
Placenta abruptio or placental abruption is abnormal separation of the placenta from the uterine wall.
