nope, it happens often...
Unless there has been a mistake in the sexing of your rabbits it is quite likely a phantom pregnancy. Phantom pregnancies and other hormonal activities can be prevented in large part by spaying both of your female rabbits!
IF YOU ARE SURE they are all girls then one is probably having a phantom or false pregnancy.
yes because to have the phantom pregnancy your body secretes pregnancy hormones which is what pregnancy tests look for
Yes. In a phantom pregnancy, the body is tricked into feeling like it is pregnant. Consequently the same hormones present in a real pregnancy will be present in the body of someone who is undergoing a phantom pregnancy, and these hormones are what a pregnancy test detects.
A horse who is experiencing a phantom pregnancy will have symptoms of an actual pregnancy. These symptoms include the horse being tired with a puffed up stomach.
Yes
The main sign of phantom pregnancy is nesting. The bunny will start to pluck out the hair on her chest and tummy to build the nest with. In the case of some rabbits they will pull hair out of a bonded mate to nest build also. You will often see a nesting bunny frantically running around with a mouth full of hay to take to her nest. If you bunny is nesting without reason (i.e. she has not been bred, she is spayed, she has not had any contact with a male) then you can pretty much be sure it is a phantom pregnancy. A phantom or false pregnancy can be detected in several ways. If you have not bred your doe you KNOW it is a false pregnancy. If she goes over 32 days it is a false pregnancy. You can palpate at 15 days and if you do not feel babies but she insists on nesting you will know it is a false or phantom pregnancy. A doe having a false pregnancy will nest just like a doe that is pregnant. I have witnessed some that tend to go overboard nearly stripping themselves naked because no babies come. The doe that you determine to be having a phantom or false pregnancy should be bred immediately. There should be no 'bonded mate' for a doe with phantom pregnancy every rabbit should have it's own cage.
The only difference between a phantom pregnancy and a real pregnancy is that with a phantom pregnancy you are not actually carrying a baby and you will usually have a period and a negative pregnancy test. You will have the same symptoms as a regular pregnancy and they can last at least as long as 7 months.Scroll down to related links and look at "False pregnancy - Wikipedia"
