My daughter and her cat, Mitzi. Actually, this is my son's cat, but he adopted my daughter. If she goes to the bathroom, he sits outside and howls until she lets him in. If she goes to school, he wanders around the house, meowing fornlornly, until she gets home. When she is in her room, he must be there, too. Anywhere she goes, he follows. Really.
In fact, all the cats follow her around like she's the Pied Piper. Except my cat, who can't stand her for some reason. I think they are jealous of each other. He thinks I spend too much time with her and she thinks I spend too much time with him and imagine being at the center of THAT triangle!
In any case, most of the cats spend most of their time in her room with her.
