Actually they all are even the smallest one. I seen her get underneath to where she got stuck and she just kept pushing and moved it. The bigger ones just walk up to it and push it. They have already moved Kong about 4 feet!
I think I'll be taking Kong out of there tomorrow after I let Cheech, the biggest male I have look at him. As being the alpha male, I suspect he will not be happy that Kong is in there and I'll have to remove it within a couple minutes or he may knock it over.
Well, Cheech has been in there all day with Kong and although I have not even seen him come close, it seems that Kong is not a statue, he moves when I'm not looking!
