Yeah, my pigs aren't the hugest wheekers in the world...they seem to "come and go" with it.
My new pig wheeks sometimes when she's having floor or lap time, and I don't know her well enough to know what it means! Maybe it means she's ready to go back in her cage or something...I dunno.
My first pig would sometimes wheek the "lonely" wheek when I left the room. Awwww! During a certain time period I would always bring her a fresh handful of grass when I got home and came in the door, and she got to where just hearing the car pull up, or the car door shut, would make her wheek like crazy.
If you want to get the wheeking started, here's some suggestions:
*Feed at the same times everyday.
*Make sure the pig hears the same sounds every time (fridge opening, or plastic rustling, or knife chopping up vegetables or something!)
*I say the SAME thing to my pigs everytime it's veggie time, in the exact same tone of voice: "What some veggies???" (in highpitched loveydovy talk, you know!
) I don't think this has ever actually made them wheek, but I think it DOES make them a little easier to catch and take out of the cage!
