Singing piggies. Normal?

[MissBetsyTrotwood]

My piggies chirp like birds. Very loudly. I hope other people's do too. Or should I be calling Simon Cowell?

I love it.

I have 4 piggies andi think only one of them sings, i googled it and its rare and means they are happy if i remember rightly!

Once she gets going though it drags on for hours!

ours also chirp, endlessly. Well, they are quiet, and then when they sense a person coming near, or hear a bag rustling, they fire it up and go on for hours. or if you have one on your lap and the other in the run, they chirrup in a panicky way until you reunite them. love them.

ours used to whistle at my dad's voice and he used to whistle back. They could go on for ages. We had one who was mute though and couldn't make any sounds.

My two sing in harmony! One has a deeper voice than the other, so when you have both on your lap and stroke them, it creates quite a pleasant tune.
