Hi Scrubby,
DS bought 2 g.pigs a few years ago. I like them a lot.
We have / had them in the "baby cage" from the store, but they need a lot more room, so made a 2ft x 4ft cage with spare materials. A even larger size for two would be better, but this is good for a large adult. This past summer we put them in a hutch outside (they love to eat grass, dandelions, fallen apples, etc).
Unfortunately, one got out of the hutch a day or two before we brought them in for the winter, so we are down to one only now. But I would still get two if possible, as after the first few months, people interact less with them, and they do interact with each other quite a bit.
Note that the cage is smelly a bit, unless cleaned more than once per week. We use fleece baby blankets (bought at thrift store) for bedding and wash / reuse them. waste material is shaken into the flower garden. If you use the commercial bedding it may be less smell, but the cost goes up. Amazon is great for delivering supplies the cheapest. They eat a lot of kitchen veggy scraps at our house, which cuts down on the amount of timothy hay that they naturally eat, and I will pull a couple of dandelions a week for them, too.
They are not noisy like hamsters, and not nocturnal, and you can give them a bath, trim nails, and cuddle up and pet them a lot better, as they are large (two hands). Mine like to sit on laps (in a blanket) while we watch TV.
They are poop machines, but it is mainly grass / hay poops, so easy to clean up on a hard floor. They can be left to roam for a few hours on hard surfaces, if they have access to food water and a hiding place. Mine don't chew anything except if left for a long time in the cage without attention.
We can leave them for 3 days or so when we travel, (like the cat). They are friendly and come out to say hi and to ask for food and pets. They vocalize in several different ways, including a purr, so are more tactile and interactive than a hamster.
TLDR -- I like them the most of any pets we have had. No cat urine all over my camping gear... No dogs that can't be left alone for more than 2 hours or they go crazy / barking.. actual pet to hold and cuddle, interactive. Low care / effort.
