I've had my too males for more than a month and they got pretty much used to me - they allow me to stroke them, only sometimes run away when I come, but really hate beign taken out of the cage, so I do it just when it's required. But I want to buy more piggies in the future, because as I know guinea pigs are very social animals and beign in a herd would make them even happier. So I'm asking you guys: is having 4-5 pigs a much bigger responsibility than 2? Of course I know I'll have to clean the cage more often, but I'd like to know if there is some danger of not adapting to the new cage or new piggies? For sure I'll need to buy a bigger cage, but I don't know how it should look like? Just let the current pigs and the new ones go into the cage at the same time, or first put there current and the new ones later? And is it a big deal for guinea pigs to build relations with new pigs?
