They are not homosexuals, instead this is a way to assert dominance over each other, this most often occurs if they haven't been together for a long time.
Guinea Pigs will often chase each other to show an amount of affection... they will also go into heat and attempt to flirt with each other around 3-6 months of age...
Male guineas get along quite happily. Although before you put any two guineas in a cage together, you might want to introduce them a bit slow so that they are familiar with each other.
Before the mating the male will chase the female around the tank until she agrees to mate. During the process the male will mount on the female's butt. Then they have a small chase then another mounting and another and another and another. They will do this a lot. I have read that gerbils usually mount about 10 times. After each mounting and when its all over they will groom each other: particularly, the male will groom the female.
They are not mounting each other for any type of sexual pleasure, rather, they are establishing which one is the dominant dog (the one "in charge"). They will do this until they both agree upon who is the leader of the two of them.
Yes, it's not uncommon for a female rabbit to hump a male, or even another female. This behaviour is part of establishing dominance and sometimes the female is the top rabbit. Once the rabbits become accustomed to each other, this behaviour should eventually stop.
No, there are no lesbian dogs. Dogs will mount each other to establish dominance, has nothing to do with sex. If a female in heat has access to a male dog, she will go there and not another female. Mounting by either sex to same sex is simply a dominance issue.
During the mating season they will like each other. Otherwise the female will attack the male.
The animal who helps each other with their young are female dolphins Also hyenas and politicians (nepotism)
No Dogs and other mammals need a male and a female.
Pretty much like humans: they help each other, hinder each other, love each other, hate each other, and so on.
NO female bettas do not fight each other
A male and a female will stand off and stare at each other. They will then back away and go towards each other again. When they get close to each other they will rub antennas for about half an hour, at which point the male will walk away from the female silverfish. If the female silverfish follows the male will fertilize the female. The female will then lay a cluster of around fifty eggs inside cracks and other small areas.
