No, a cat that has never had kittens cannot nurse.
When kittens are very young they nurse to get milk from their mother, but this is a very special time for the kitten to be loved, cuddled, cleaned, etc. by their mother. They have fond memories of being taken care of by their mother. When a male cat comes along (especially one that is friendly with the kitten) the kitten will try to nurse for comfort and security. There is nothing wrong with this behavior my kittens do this occasionally.
No, a non-pregnant cat cannot nurse kittens because she will not produce milk without being pregnant or recently giving birth.
The male cat doesn't take part in the raising of the kittens it really doesn't care about the kittens just the female and the sex
No. Cat queens do require a male cat to fertilize them before they can have kittens.
They get in heat and a male cat impregnates her.
Yes but take it slow on introducing the kittens to th father or male.
Yes, hermaphrodite cats can have kittens. While it is rare, a hermaphrodite cat may have functioning reproductive organs and be capable of producing offspring.
orange is sex linked dominate, a female orange cat will almost always have a few orange kittens, and a male orange cat can have orange daughters --- If the orange one is the mother, all the male kittens will be orange. If the orange is the father, you wont get any ginger kittens but you will get tortoiseshell female kittens.
Pregnant. A female cat is called a Queen and a male cat is a Tom. When the Cat is having her kittens, it is called Queening.
A cat who has not recently had kittens cannot nurse. But if a cat just recently weaned one litter, and a new kitten is brought, she may be able to start producing milk again. It is not uncommon for a mom to accept another cat's litter--- maternal-mothering instinct is powerful.
Probably, if you have a female and a male and nether are spayed or neutered.
