Obviously one of the rabbits is a female and not male.
YEAH
The term bilateral means on both sides. So in this phrasing it just means that both testicles have descended from the abdomen into the scrotum. This is what is supposed to happen. It is considered problematic if both testicles have not descended into the scrotum by the time a boy is 1 year old.
No, rats have intercourse to have babies, and there are both male and female rats.
I'm not certain if you mean that can she get pregnant without a male rabbit, or can the babies be raised out side of a "family unit", so I'll answer both. No, she must be bred by a male to get pregnant. And no, rabbits don't raise babies in a family unit. All moms are single moms and the prefer it that way.
yes they can both be pretty mutch any age
No seperate them most likely they will kill each other or each others babies.
Yes. But reproduction can happen even it only one has descended into the scrotum after birth. They are both used if a male has had them both descended into the scrotum, but only one is required for reproduction.
Rabbits typically have a gestation period of about 28-31 days, regardless of their age. So, if an eight or seven month old rabbit becomes pregnant, it will take around one month for them to give birth to their babies.
A ruptured or "squished" testicles, can cause infertility (sterility) if medical attention isn't provided immediately. Ruptured testicles can sometimes be repaired, if immediate medical attention is provided. If one testicle is ruptured beyond repair, it is still possible for the male to have children, because males are equipped with two testicles. But, if both are ruptured beyond repair, the male, will become infertile (sterile).
Lots of things come in pairs: Hands, Legs, Eyes, Parents, Testicles...
Yes. In fact, mother rabbits often do eat their kits. They do this when they become frightened thinking that they are putting them back inside their womb to "re-birth" later. Gross, I know! Have had this happen many times with rabbits that I own.
It is usually not advised to keep two male rabbits together, especially if there are females nearby. However, if the pair are acquired together as youngsters, like littermates, and neutered before they reach sexual maturity, the chances for successful cohabitation greatly increases.
