It becomes stiff and apears dead.

With syrians you may see a milky discharge (just small amount) and freezing in the mating postition with back end up in the air and sometimes a 'Musky' scent. They also come into heat every 4-5 days except during winter.
One way is to gently but firmly run your finger along her back. If she sort of brings her body close to the ground, and "freezes" (not moving) then chances are she probably is.
i don't know if i get your question but i think that is urine.
You'll notice a tiny spot of blood on her vagina.
do not place under heat lamp it may kill hamster!!!
Well a hamster can go into heat right after she gives birth.
Red
It means that your hamster is above room temperature.
It depends on the hamster, so i dont know.
You don't, unless you know the female is in heat and ready to mate. Otherwise keep them apart at any other time.
Your hamster usually is in heat when you pet it by its lower back. Your hamster then will slowly become stiff, point its tail up, hunch its back and will try to stick itself to the ground. This is not something to worry about, it happens to a lot of female hamsters. People also say this happens in a young age (1 and under) but that is not true. My hamster is about 1 and a half and it happens all the time. This also means they want a mate... now clearly that cant happen due to the fact if you gave her a mate she would most likely eat him. So why would a female want a mate if she will eat him? I'm not quite sure. But hamsters usually begin heating every 4-5 days no matter what age. Hope I helped! BTW when your hamster is in that hunched position, continue petting her. They like it.
You do not. Hamsters go into heat by a natural cycle all on their own.
What is a hamster that has no legs called? A furball.
If the female hamster is not on heat they will not mate, so just separate them until they're ready.
