Hi It really depends on the age of the first litter? And age and health of your doe?
Rabbits gestation period is approx 31 days, so worst case your litter are approx 4 weeks old when your doe is littering again.
I would hope that your kits would be starting to eat solid and use there water bottle at 4 weeks. My best advise would be to remove the older litter, It maybe necessary to hand feed with goats milk or puppy / kitten formula
The younger litters best chance is with your doe, hopefully if she is in good shape not too old and hasn't been over bred she should be able to successfully rear this litter herself.
when she bangs another rat
About 8 hours after givin birth to the previous litter
depends on how much you feed him or her
Why would you bury a dog in litter
No, she will eat them. Even if her own litter is 'tainted' with another scent this may happen, such as not covering your own scent with the smell of the bedding\ substrate before handling the young litter.
Most often, by the time the next litter comes along, the previous litter is old enough (eight months) to fend for itself, and has been sent off about its own business.
Rubbish
No
Well it usually takes a couple months not very many so if you have a boy and a girl rabbit i would separate them before the women rabbit gets pregnet by the male rabbit so i would do it quickly before you have another litter and it happens again! and that wouldn't be very fun! would it?
Cat feces will accumulate.
It is really a personal choice as to whether your doberman has a litter before the dog gets spayed. If you have the puppies a home and they will not be a burden, then let the dog have a litter.
yes. But wash your hands first.
