Hi i had never seen my pigs drink from their water bottles. They always had lots of fruit and veg and as i have only had them over the warmer months they have been out on the grass alot. Went away for a few days and took them with me in an in door cage so they only had hay and not so much fresh stuff and no fresh grass. Over these few days i saw them drink. If they are weeing ok and fresh water is avialable i shouldnt worry.
I worried about that too but I guess Vash gets a lot from his veggies since we put water on them. He will drink from his water bottle but not as much as he once did. He is always peeing so I don't worry too much plus I see him licking water off his lettuce. I would not worry too much as long as they are healthy and peeing.lol
I knew a breeder who never supplied his pigs water they got all theri fluids from his own specially grown hay and seed he soaked it to germinate a then left it to grow in a dark place, never really listened much but i thought it was a lot of work for not giving them drinks, but i have heard of it happening, mine all have drinks, some drink gallons others a drip
Yes, I have 6 pigs; some drink, some don't. I too think it is because they're is alot of water in their diet already; like grass, which is what i regularly feed my pigs with.
One time, I saved one of my guineas called Barb becuase she was out in the sun and nearlly got heatstroke. So i gave her a drink through a syringe and she was fine.
They also tend to drink when you're not near them; I think it's just because that's the way they're like in the wild i suppose.
