From my studies i think that you can see Male Bunnies Kidneys, but for Female Bunnies you cant.
Spay and neuter both your bunnies.
Breeding or mating.
if a male is separeted during mating it can die
if the mating is sound yes she will still have kits but the best way is to put the female in the bucks cage as the smill of the bucks hutch entices her to mate
After mating, yes. After the female has given birth to the bunnies, no. If the female gets pregnant RIGHT after giving birth, her health will go down. Best to wait a day or two before mating again. Better yet, go and spay and neuter that couple.
harem mating is one male to several females.
yes they did eat them after mating
No. The Northern quolls do not stay together after mating. The male actually dies after mating.
They die
The mating itself is a type of external fertilization, but the mating position is called amplexus
Either it is not mating season and/or the male is fixed.
