I'm sorry if this is in the wrong place, and I did a quick search but I couldn't find exactly what I'm looking for, but my piggies never wheek! I have had them around a month now, and they are totally normal in every way, they popcorn, run laps, get excited at rustling bags etc but they have never wheeked? I'm probably being selfish at wanting them to be excited by me, but are mine unusual in this or do a lot of piggies not wheek? x
