Okay, the two boys were getting along fine on floor time, some strutting and mounting, which is perfectly normal. But then, some other boys were on floor time*they were seperated by grids* and started making a huge rumble. I was in the middle of a major cleanup and couldn't take my time out to put them back in their cage. Then the little one got frustrated and started to bicker. I thought all was well, but then when I put them in the cage they went at it. Not as a big ball type, just annoying each other to the fullest extent and then chittering very loudly. This is after I attached the yellow cage to the other yellow cage. I will be posting those pictures shortly. So I now have Chubby in a large cardboard box and am making him a 2x3 in a few days. He's getting floor time about double the time he got it before, so he's getting about 6 hours of floor time- unsupervised, only because I can not watch him the entire time. The boars in the yellow cage are enjoying themselves, which is great. I now have 3 guinea pigs that would rather be alone or with a female- Simon, Chubby, and my 4 week old male!! I'm making 2 2x3's for Simon and Chubby. It'll be green with either chrome or white grids, I will also post those cage photos soon. Simon is in a cage equivalent to a 2x2. He also gets the same amount of floor time as Chubby, 4-6 hours each day. Can't wait till I post the new cage(s) photos!!
