Don't forget to quarantine any new arrivals for at least 90 days before introducing them to any established pets
There is always a chance that they might not get along and it may not present itself in outright aggression
Dominance that prevents one of the Leos from feeding-resting on the uth-etc, can also occur
Some Leos do not do well with others-some tolerate each others presence and when kept in groups they need to be carefully watched for any problems
They really do best kept long term alone
just my 2 cents
