Hey guys! My two baby female Guinea pigs won’t stop nipping at each other so I divided their cage for a couple days and finally they’re back together today. They were extremely happy at first, popcorning, but then began to start fighting again. What should I do? Should I just let them be or divide it once again but extend it for a longer period this time? Upon putting them back together, I also added new tunnels and hides that were never there before. In total there are 4 hides/tunnels. Are they getting territorial over the hides? My cage is also 3x4 for two female Guinea pigs so I believe that space may not be the reason for their fights. Any replies or advices would be greatly appreciated!
