After months of deliberation, our family decided recently to adopt a lovely female rat "Bird"... We will be going to pick up her buddy later this week. We have a dog and three cats. Introducing a rat into the family was a hard decision, mostly for her/their safety, hoping that they are not looked at as food or a toy to one of the cats. So far the cats seem interested, but don't try to pry at the cage. Our dog is gentle and just watches her. So far, we are just in love with her.
