I have a Yellow Foot senior citizen and she's awesome! Great personality.. really interactive with us (she thinks my toes are edible and will follow me all around the house or yard, trying to eat them) ...and she's not huge.
My beloved Cherry Head Red Foot girly was my heart! Such a sweet girl ..even hanging out with us, lying on our chest and listening to us read. I miss her!
I have a female Russian (another rescue ..all 3 of my girls were, actually), but I'm not overly impressed with her, nor her me. She's not a big tort ..about 7" diameter.. and she's not really demanding. She just doesn't seem to care for me much.. none of us, really. She is loved and looked after, but she pretty much does her own thing and doesn't want to be bothered.
As for turtles, what do you think of Smooth Soft Shells? I've read and heard different things about their adult size, so I'm hesitant.
