I have two male guinea pigs Ziggy and Petro. I have tried putting them in a cage together twice with no luck. Before putting them together I bathed them together and put them on the floor for several hours together. When put in the cage (first was 7 feet by 5 feet wide, second was an L shaped- two 2.5 foot by 4.5 foot) and they are fine the first day or so but start fighting. The second attempt ended in one drawing blood. This was several months ago. Should I try to put them together again or just keep them seperate?
