They do this do establish dominance, and mark each others sent on one another. Since their scent glands are down there.
um no, only female gerbils can
Male gerbils, when they sense that the female is in heat, will start rhythmically tapping their foot on the cage floor. You can see this "thumping" behavior if you look closely at his back feet, and sometimes you can hear it. If the female is receptive to him, the gerbils will go through a mating ritual of "chase and tag" for about two hours before settling down again.
Male gerbils can be neutered, but it is not recomended. Female gerbils should not be spayed. In general male gerbils should not be neutered unless there is a good reason for it.
yes
Female dogs may engage in self-stimulation by licking or rubbing their genital area. This behavior is a natural part of their grooming routine and is not necessarily a sign of sexual arousal.
Only if you give them crank.
Yes, female dogs may engage in behaviors that could be considered self-stimulation, but it is not the same as human masturbation. It is a natural behavior for dogs to explore their bodies and relieve themselves of any discomfort or tension.
Yes. Male gerbils, no matter how old they are, can impregnate female gerbils. Most female gerbils can no longer conceive after 2 years of age. Either way, it's never wise to put a male and female together unless you intend to breed and provide for several litters. Gerbils are not easy to find homes for.
No I have two female gerbils (Minnie and KE$HA) and KE$HA is clearly older and they get along fine.
...You are kidding, right? Gerbils are mammals; some of them are male, and some are, well, female. They reproduce the way mammals do.
I'd be interested to know where you heard that as I've done necropsies on female gerbils and have not found that to be true.
About 28 days after the female gets pregnant.
