Not common, but it is possible.
Yes. A cat can have kittens from different fathers in the same litter.
my female dog is in heat but she doesn't let herdself get breeded. What should I do?
Well they bleed but only for about a week. They are still in heat though they are not bleeding
it can happen. This has even happened with females who were fixed. However, a female dog MAY still be in heat even if she is no longer bleeding. Heat cycles usually last 3 weeks. Be sure to keep the female away from any intact males for her entire cycle
Yes. My two cats were in heat when they got fixed. The vet will charge you extra, though.
no
If there is another female around she can get domanate of her surroundings. A female pit in heat can be aggressive and even more so if she has has a litter recently.
Most females will only allow a male to mount them if they are in heat as this is the time when they are most fertile. Although some females will allow a dog to mate them whilst they are not in heat, there is less chance of the female getting pregnant.
Gerbils go into heat ever 4 day. There are no outward signs that they are in heat, unless a male is in the tank (in which the male will attempt to mate with her)
Some do, So be careful because a male can get posessive with the female and may hurt any puppy nearby.
No. The compressor is needed to run in reverse in order to pull warm air from the outside to heat the home.
Yes, a female no longer goes into heat if they are pregnant.
