Our rats, Bubonic and Skooter, were males, were raised together and died within a month of each other @ approx. age 2. They both weighed over 2 lbs. Can you say too many treats? They weren't meant to be designer rats, they were snake food that became pets; and great pets they were. Ours were potty trained as well. Always went back to their cage to do their business.
Rats beat hamster hands down for pets, IMHO.
