Thanks for posting. I'd love to have a pure-breed maine coon one day.
Surprisingly, my scottish fold Graham is the most dog-like behaviour among my cats. She follows me around, "talks" to me, wants endless belly scratches, fetches, sweetest amongst my pack of canines and felines, and best of all, she is the most destructive.
Sounds like Arnold would be a good playmate for Pantera. She's well known for breaking things and tossing Pimenta around like a ragdoll. When she goes into "play mode" Pimenta keeps her distance (Pimenta is still a bit afraid of Pantera)
