Hello, so I am doing a research before buying guinea pigs and I saw that they are herd animals so they should be living with at least one other guinea pigs but my mom said it's my first time caring for guinea pigs so she won't let me buy two. She said I can buy my second one if she saw me taking proper care of my first guinea pig. Will it be fine if I only buy one guinea pigs and maybe add another one later when my mom lets me? Any advise is welcome! Thanks
