if my rabbit is pregnate

Question

Answer
Dear Matthew,

Your bunny might be having a false pregnancy.  But if you are in the UK or Europe, the wild rabbits are the same species as domestic ones, and a wild male might have visited if your female was outside.  

If you're in the US, a stray feral rabbit might have been around, but the local native wild rabbits are not capable of impregnating a domestic rabbit, as they are different species.

If your bunny is pregnant, I hope this will help:

But be sure to read:

so you'll know what to do for her health and safety, as soon as you can.

Hope this helps.
