Okay so I did shower intros for my 4 rats to 2 new boys. The two girls and less dominant boy all took to the new boys immediately, within 30 minutes i moved them to a cat carrier and they all were laying on top of each other and whatnot. But my dominant boy Pepe did not take well to them. At first I thought everything was going well, until suddenly Pepe started chasing one of the new boys and I was scared he was going to hurt him so I grabbed Pepe and he BIT ME. I was in total shock, never in my life have I been bitten. He bit me so hard, there was blood spattered all over the shower and I had to take everyone out and hose it down. Now everyone but Pepe is playing and free ranging. What do I do from here guys?? Help!
