It's a dominance thing; the humper is showing the humpee who's boss-dog.
Because he wanted to mate her but didn't know she was fixed.
For same reason your husband humps the neighbor's wife after a vasectomy. Because he can.
First of all no girls are neutered. Boys are neutered. Only in dogs and cats. Not people. If you have a female pet, it has been spayed, then no, its heat cycle will stop.
Male cats yowl to female cats and urinate when they are in "heat." You say he's neutered (fixed)? Well, he shouldn't be in heat AT ALL if he is neutered.
Yes, they can tie and if that happens they should be supervised but not pulled apart as injuries can occur. There is no chance of pregnancy if the dog has been neutered over a week (some semen survive after neutering but quickly die off due to body heat.)
Male cats don't go into heat. Male cats can be neutered at any time. Female cats may also be spay at any time. If you suspect your female cat is pregnant, inform the veterinarian in advance.
It just depends on their instinct and "personality", I'm pretty sure. It's just how they are.
Male cats do not go int heat, neutered or otherwise; heat is a characteristic of the female oestrus cycle. Even a properly neutered male may still respond to a female in heat, out of habit. If a cat has learned to spray before he was neutered, he very likely will continue after he has been neutered. It likely will be less frequent, but it can still happen.
Cats are very seldom castrated; a neutered cat does retain his penis. And a neutered tom will still cover a queen in heat, because his reactions to her scents and actions will still be in place.
If they aren't neutered, yes.
Yes, a female ferret can be neutered to keep her from going into heat.

Yes; a recently neutered tom will try to cover a female in heat. He won't be able to impregnate her, but he'll still have the habit patterns and chemical responses that make him try.

I think you mean Neutered? :P Well cat's get Neutered because the owner does not wish for the cat to get other female cats pregnant. Neutering is for Male cats and Spaying is for Female Cats. If you would like to breed cats, then don't get them neutered/spayed! If you do not get your cat neutered, it doesn't mean that it's going to get female cats pregnant, you'll just have to keep a close eye on them. I have noticed that when a cat is in heat, it gets rather annoying! But that's just me! :)
it is in its natue for a male to go after a female \
Spaying is for female animals. Neutering is for male animals. Both procedures make it impossible for a pet to reproduce: a spayed female cat/dog cannot get pregnant, and a neutered male cat/dog cannot impregnate a female.
