Typically, a cat will not show signs of being in heat once they have been bred.
YES!
No. Only a male can impregnate a female. No female mammal of any species can get another female pregnant. For mammals that have a "heat" cycle, being in "heat" is required for pregnancy by a male. If such a mammal (a dog for instance) is not in heat or doesn't have a male partner, pregnancy is not possible.
Signs may include increased interest in the female dog, heightened awareness of her scent, frequent licking or sniffing of her genital area, and possibly attempting to mount her. These behaviors can indicate that the male dog may be responding to the female dog's pheromones signaling she is in heat.
Yes. Just don't talk to her
Yes.
No she cannot be brought into heat by a male being around her. She will cycle every 6 months on average. If she is near another female in heat, that might bring her into an earlier heat.
It is called being in heat or in season, is when the dog can become pregnant. No there should not be any signs of a fever. The normal temperature in a dog is 101 to 102 degrees. If your dog is running a fever while in heat, I would take her in to be checked out by a Veterinarian.
it is the period in time when an animal/mammal (female) is ready for sex without being in heat period the female will not mate with any male
Yes but it has a better chance halfway through heat
They yowl loudly and incessantly when they're in heat. A cat in heat will also sort of crouch close to the ground, and/or drag their behind along the ground.
Yes, they release pheromones.
