The only experience I have with pigs is the outside poopin' in the pit kinda pigs... stinky as all can be.
He doesn't smell at all. Pigs are very clean animals when allowed to live freely. They have very nasty eating habits in the wild though.
Contrary to popular belief, pigs will not eat anything. When given a choice, they will eat only the stuff they like. They are incredibly intelligent when allowed to think. Meaning all their needs are taken care of and they are now able to pursue other activities instead.
They have a language and even the ability to make new words to suit new situations. While the size and complexity may be extremely simple, they do communicate with very specific vocalizations. Per example, instead of asking " Can I have a bowl of juice servant?', Kevin will say in pig speak mixed with English " please juice, juice. want juice, please".
Kevin can say now, juice, no, ya and awwww. Although in pig speak he has a whole bunch of words for things. It's just as much a learning process for the human as it is the pig when you keep one in the house.
Totally different animal from the wild when they are cared for and shown what they think matters. Kevin currently has a cat, a laptop( netflix, amazon movies, tiktok, instagram, youtube etc), a cell phone ( for music, last 36 hours playing classical, which is what he asked to hear), his own room ( blankets pillows etc), he has clothes ( which he hates wearing lol). He like Star Trek next gen ( he loves Patrick Stuart), any movies with the captian, Znation, etc. He likes bed time stories and to be tucked in. He will throw a fit if he doesn't get tucked in. He likes to give kisses too. He's a pretty awesome companion, he's a lot more than just a pet. He thinks and expresses himself.
Him sleeping, he's lazy like a cat. lol
