They are, completely and utterly weird. My mother has 3 of them, one of them Trixie constantly constantly constantly wants to eat to the point where if you gave her unlimited food she would eat it until she puked and then continue eating and would puke again and continue eating again and again, she never ever stops and she never gets fat! The other one Fiona is like a deer, constantly scared running away to hide, you have to put the food under the bed or under a couch for her to eat, my mother calls her the “phantom cat” because you never see her, and the other one Ian constantly wants to get petted, it never ends, he sees someone coming he jumps on the table and hounds you until you pet him or climbs all over you if you sit down until you pet him. They’re all completely neurotic.
