The whole belly rippling is contractions.
She is looking for a quiet dark out of the way place. Can you direct her to one that is safe? She will not want to be around the other animals when she gives birth.
Advice needed - since last night my girl has been getting onto every high place she can. Each time I climb up and put her down on the floor out of concern that her jumping down could hurt her or the kittens.
I tried confining her to one room with food, water, litter box. She became so agitated I had to let her out. What should I do? I don't want her to hurt herself or her kittens.
