Does Cosmo like being pet? I pet her on the right of her head, sort of the "shoulder" area. She sort of nibbles on my finger when I pet her, but she doesn't move away. She doesn't seem uncomfortable, but I can't really tell.
I just tried petting again, but this time, Cosmo "grabbed" my finger with her foot, and started nibbling at my finger. And then Lulu, who was sitting next to Cosmo, started nibbling also. What are they doing?
