Thank you! For the most part I leave the cage open and they free roam in their area. Persephone is my explorer rat. She's the reason my storage space was converted to a playground.Welcome. Lots of people here with great information and support. Love the little playground you set up on the outside of the cage. Fun!
I'm really not sure. I got them from the Petco I work at. Persephone and Echo both weigh about 180 grams, though Persephone was labeled as a "small" rat and Echo a "medium" rat.So adorable. They look really small. How old are they?
