Your little guy will start talking when he feels comfortable in his surroundings. It sounds like he lives alone so right now he doesn't have anyone that knows his language to learn from, if you know what I mean.
I don't think they would mind soft whistlingThere are loads of ways to "talk" to your piggies. I usually smack my lips (and talk in an embaressingly high- pitched voice...
)
yeah, I just wanted to make sure there was nothing wrnog if he is not talking to me.. He likes me just isnt squeaking at me..
