My Cheeto has terrible manners about everything, and I'm unsure on how to teach her to behave. She races out the apartment door into the hallway (thank goodness it's not a door to outside!), jumps on the counter, won't stay away when I'm eating, and gets excited and bites and scratches. I know lots of this is from being a kitten and everything is new and exciting for her, but I'd like to teach her some basic rules around the house. How do I start????
