We had two pet rats, hubby and I. They are like little dogs lol. I played with mine more than hubby played with his. His was a little snippity. Mine would sit on my shoulder, lick me, and was just a big huge cuddle bug. He loved to come out and play. My brother had two rats and my other brother had one too. My youngest brother didn't like his, becaus eshe peed on him once, and was beginning to get a little thin so I took him from my brother and fattened him up. I gave him to my son's special ed class aid who brought him home every night and on weekends and holidays. He was huge and sweet. My other brother's two rats were very sweet too. He took better care of his and had them in massive cages. Both were girls but they didn't get along. The one ended up dying. By the time my brother came to have her, she was seven years old. She died off massive tumors. By the time he had her put down, she was skin and bones and the tummor on her tummy was so big her feet didn't reach the ground anymore. She came to her name and had free run of his room and access to her cage at all times. Neat personality that one. The other, he still has and she's a little hyper. You need to pick one with a personality that suits you. I would shy against pet store rats, they're bred for the snakes. If you get one, a breeder is cheaper, they can pick one that suits you, and they have a bigger selection in colors. Ask me anything, we've had rats for as long as I can remember lol.
