My fawn doe mated on the 19th April. Yesterday she wasn't her normal self. She's HUGE and I know I'm inexperienced but I've had two other litters (8 babies the biggest number) and this is worrying me. Today she can hardly move. Her breathing is extremely laboured, ears flattened and her coat is really 'staring'. I know my date is right because that's the first day she was put in with the male. She's also doing occassional loud squeaks. I've seen her weeing but not pooing yet and she certainly isn't eating because she isn't moving around. Is she just extremely pregnant? Is there anything I can do? What can it be? She's my favourite mousey, I don't want to lose her.
