A cavy newbie means you've been on this site for less than 30 days, being a slave means you've been here for more than 30 days. You can donate some money to be a cavy star or champion. If you break forum rules you could get the title of cavy caged. It's just a title to show others how long you've been here/contributions to the site
According to the cage size chart, 14 sq feet is the minimum for 4 girls, so unless there is dominance issues or you really want to expand. Your husband is right about it being enough space
Okay, thank you. I don't have any dominant girls, they all seem to know their place and the boy is in his own cage next to the girls. Does he need a friend or is he okay by himself? My husband holds and plays with him alot because he is by himself.
