I myself can technically have 11-12 rats because I have a large ferret cage (ferret nation 142). I think persoanlly though I could handle maybe 8-10 rats. The only thing that really limits how amny rats can be together is the owner not being able to handle as many and cages not being big enough. I know one woman who has had groups upward of 19 or so. Yes they are the opposite of syrians when it comes to being social. Thanks vinjashira

Thanks zippy. I am getting so stressed and nervous about this whole thing. >.<
