Hi everyone! I'm in dire need of help. I've had a pair of rats before that were shy at first but were young and fairly easy to tame. My local shelter has just received over 80 rats, adults and juveniles. Thankfully other rescues have stepped in to help take some of the rats but they really only took the young ones and the friendlier females. The ones who are left are all males. We are in the process of neutering all 50ish of them but they have had little to no handling and most are aggressive. I've been bit numerous times by these guys. I need some advise on how to tame them and get them use to human handling or else they will never get adopted! We are in desperate need of help so any tips to help get rid of the aggression would be helpful. If I stick my hand in the cage the alpha males will run, bite, and latch onto my hand. They are in large 4 story Midwest cages I believe with about 10 rats in each. We've been giving them treats and fresh veggies everyday and I've been feeding them low fat low protein dog food off a spoon to try and get them use to my presence.
