I got a new friend for my guinea pig about a month ago, and the introduction went fine. there was chasing, like all normal intros, but my guinea pigs are still chasing after a month. They dont fight or bite, just nipping. (without blood or teeth).I make sure Pebbles (my newest Pig) isnt bullied by putting two water bottles, two food bowls with pellets and multiple hideys. We have the C&C 2x3.5 cage (medium), so it is large enough for my two sows but on the C&C website it says they need to be bonded, so it wont be big enough for a new pair of guinea pigs .Should I get a Small cage and conbine it to my medium? Do they need to be seperated, or should i give them more time?
