First I just want to say hello. This is my first post, but I've been reading posts here for a few weeks now. Anyways, my piggie is very still all of the time. He is fairly new and I figure he should run away from me when i go to catch him, but he just kinda sits there and lets me get him. I just thought he was laid back, but today I looked under his head where he was laying and I could tell he'd been there for a while and there was white stuff (liquid) on the black towel where his head was. I don't know if it came from his mouth or his rear-end. Has anyone had a problem like this before?? He also never really plays with my other 3 boys. He usually just does his own thing. Is he sick? Should I take him to the vet? Please help.
