If a piggy calls another piggy and they dont answer?

[teddy2011]

I was just wondering - what would it mean if one piggy wheeked for another piggy and they didn't answer?

Does it mean they have no interest in that pig?

Thanks

Mine have done this before, but no idea what it means, mine only did it when they were trying to find one another though.

Mine used to do this! When I held my eldest boar (squeaky) my younger one (bubbles) used to go crazy! He used to squeak and chew the bars and try to climb the bars and dig under them and just go generally beserk. Squeaky showed no interest and couldnt care less when Bubbles was out of the cage though. I have no idea why they do it, I thought it was something to do with Squeaky being the dominant piggie? xx
