Pigs hair stands up because they are either happy, content, feeling love or may be also scared, aggression etc.
I've had pigs that when happy the pigs hair would stand up and it was always a sure sign that the pigs were happy.
But it can vary from pig to pig as to exactly why the pigs hair is standing up.
When it comes to pigs squealing the pigs can squeal pretty loud.
A pig can squeal as loud as 115 decibels which is 3 decibles louder than a supersonic airliner.
If you're sensitive to sound then being around a lot of squealing pigs will hurt your ears and being close up to pigs squealing really loud could harm your hearing as well if you're around them too long without earplugs.
Some pigs do cuddle with people and some pigs do not cuddle.
It's all up to the individual pig but when I had pigs on the farm as a kid most of the pigs we had would love to cuddle and play.
Pigs for the most part are very affectionate animals although they may not look like they are.
Most pigs are cuddly and love to cuddle.
When it comes to cuddles and cuddly from pigs most pigs are willing to cuddle and are pretty affectionate animals.
Some pigs show affection towards people better than others and some pigs may not be very affectionate and want to cuddle.
All pigs have their own feelings towards people just like humans have feelings towards other humans and other animals have their own feelings.
Some pigs do play with toys.
Then again some pigs may just want to be lazy and not energetic but it really is all up to the individual pig.
I've been around pigs on a farm as a kid and the pigs we had were mostly playful and energetic pigs and they had dog toys that they would love to play with.
I had a pig on the farm that would chase after a ball and then roll it back to me and then want me to throw it again.
Or I would throw a Frisbee and the pig would go after it and bring it back to me.
Then there was a pig that we had that was so lazy and didn't want to do much of anything.
Just like some people are energetic and some people are not.
Pigs are the same way as are some other animals.
