I haven't posted in a while, but I have two 6 month old male ratties from the same litter living with me at home. I was walking around in the petstore and in this cage was a big male rat. I asked the employee where he came from and he said that the rat was surrendered with his cage and two other buddies. His buddies were apparently fed to snakes because they weren't friendly enough. I asked if I could see him and he was such a sweet heart. The petstore people said he was 2 or 3 years old(he did look about that age). They said they would give him to me with all his things including the cage for $20. I am trying so hard to hold out. I would ask my mom if we could adopt him but her only concern is that he will give a disease to my rats at home. What do you think I should do? I can't decide if I should get him or take my moms advice and just stick to my current mischief.
